FIELD

The disclosure relates to biochemical compounds for improving plantproductivity and/or harvestable crop value and methods of application.

BACKGROUND

Plants produce both primary (essential) and secondary (non-essential)metabolites during growth. Secondary metabolites are not necessary forthe plant's survival but are small molecules that contribute to plantgrowth, development, defense, and reproductive capabilities. Numeroussecondary metabolites, including alkaloids, terpenoids and isoprenoids,and phenolics, among others, have commercial value in industries rangingfrom nutraceuticals to pharmaceuticals to agrochemicals. Previously,elicitation has been utilized on cell suspensions and in vitro plantcultures to induce the production of some plant derived secondarymetabolites, but these applications have generally been limited to thelarge-scale production of plant products that are not adequatelyproduced in planta.

Thus, there remains a need for compositions and methods of increasingsecondary metabolites in planta.

All publications, patents and patent applications, including anydrawings and appendices, are herein incorporated by reference to thesame extent as if each individual publication or patent application wasspecifically and individually indicated to be incorporated by reference.

The following description includes information that may be useful inunderstanding the present disclosure. It is not an admission that any ofthe information provided herein is prior art or relevant to thepresently claimed disclosures, or that any publication specifically orimplicitly referenced is prior art.

Definitions

As used herein, the term “about” refers to plus or minus 10% of thereferenced number, unless otherwise stated or otherwise evident by thecontext (such as when a range would exceed 100% of a possible value orfall below 0% of a possible value). For example, reference to anabsolute content of a particular cannabinoid of “about 1%” means thatthat cannabinoid can be present at any amount ranging from 0.9% to 1.1%content by weight. The term “about” also refers to plus or minus a daywhen referring to a length of time measured in days.

The term “a” or “an” refers to one or more of that entity; for example,“a gene” refers to one or more genes or at least one gene. As such, theterms “a” (or “an”), “one or more” and “at least one” are usedinterchangeably herein. In addition, reference to “an element” by theindefinite article “a” or “an” does not exclude the possibility thatmore than one of the elements is present, unless the context clearlyrequires that there is one and only one of the elements.

The International Code of Zoological Nomenclature defines rank, in thenomenclatural sense, as the level, for nomenclatural purposes, of ataxon in a taxonomic hierarchy (e.g., all families are for nomenclaturalpurposes at the same rank, which lies between superfamily andsubfamily). While somewhat arbitrary, there are seven main ranks definedby the international nomenclature codes: kingdom, phylum/division,class, order, family, genus, and species.

As used herein, the term “elicitor” refers to any molecule thatstimulates a response in a plant. Elicitors may be exogenous orendogenous, and may for example, activate the production of a secondarymetabolite.

As used herein, the term “jasmonate or jasomates” refers to a class ofcompounds modulating plant responses to abiotic and biotic stimuli. Thecompounds may be produced endogenously in a plant, exogenously appliedto a plant, or of synthetic origin, and include ethyl jasmonate,jasmonic acid, methyl dihydrojasmonate, cis-jasmone, transjasmone,methyl (+)-7-isojasmonate, dihydrojasmonate, prohydrojasmone,isojasmone, methyl dihydro iso jasmonate, and their homologues oranalogues, isomers, derivatives or conjugates thereof.

As used herein, “biostimulant” refers to substances and/ormicroorganisms whose function when applied to plants or the rhizosphereis to stimulate natural processes to benefit nutrient uptake, nutrientuse efficiency tolerance to abiotic stress, and/or crop quality,independently of its nutrient content.

As used herein, a “high-CBD” Cannabis line refers to a Cannabis varietycapable of accumulated at least 5% CBDmax by weight in the trimmed driedinflorescence. Thus, a “low-CBD” Cannabis line would exhibit less than5% by weight in the trimmed dried inflorescence.

As used herein, “marijuana” refers to a Cannabis variety having greaterthan 0.3% THC. A marijuana variety capable of accumulating greater than10% THCmax by weight in the trimmed dried inflorescence is hereinreferred to as a “high-THC” variety.

As used herein, “hemp” refers to a Cannabis variety having less than0.3% THC.

As used herein, “altering” or “altered” may refer to an increase ordecrease relative to a control value.

Overview

The disclosure relates to methods and compositions for altering theproduction of one or more secondary plant metabolites comprisingapplying an effective amount of at least one elicitor, wherein theelicitor is a jasmonate or a salicylate, and combinations thereof. Thedisclosure further teaches compositions comprising effective amounts ofthe elicitors disclosed here. The disclosure further relates to methodsand compositions for controlling plant pathogens, such as fungalpathogens.

Elicitors

Certain biochemicals are known to function endogenously within the plantand play roles within plant hormone signal transduction. Jasmonic Acid(JA) and Salicylic Acid (SA), which correspond to the Jasmonic Acidpathway and Salicylic Acid pathway in higher plants are responsible formodulating plant responses to abiotic and biotic stimuli. Thesebiosynthetic pathways derive from alpha-linolenic acid metabolism andphenylalanine metabolism, respectively, and in some plant species areantagonists of each other; when JA pathways are upregulated, SA pathwaysare repressed, and vice versa. This phenomenon can be described in onesense by the chemical's relationship to the octadecanoid pathway, whichis responsible for the production of jasmonic acid. Salicylatesdemonstrate negative crosstalk with jasmonates and likewise areconsidered inhibitors of the octadecanoid pathway.

Jasmonic acid is one of several endogenous lipid-based octadecanoidderivatives that are known to act as elicitors of plant defense, alongwith its methyl ester (methyl jasmonate, MeJA) and other derivatives(Saniewski M. (1997) The Role of Jasmonates in Ethylene Biosynthesis.In: Kanellis A. K., Chang C., Kende H., Grierson D. (eds) Biology andBiotechnology of the Plant Hormone Ethylene. NATO ASI Series (3. HighTechnology), vol 34). Jasmonates generally follow the same fundamentalbiosynthetic steps in plants, starting with the oxygenation ofalpha-linolenic acid by lipoxygenase (13-LOX), which cyclizes to formallene oxide and then rearranges to form 12-oxophytodienoic acid(12-OPDA), which is then transformed into 7-iso-jasmonic acid viaR-oxidations and can isomerize into JA. JA can then decarboxylate intothe bioactive cis-jasmone (CJ), conjugate with isoleucine to produceJA-11e, or be metabolized into Methyl Jasmonate (MeJA), among others(Matsui, R., et al. Elucidation of the biosynthetic pathway ofcis-jasmone in Lasiodiplodia theobromas. Sci Rep 7, 6688 (2017)).

Jasmonate derivatives, or derivatives of the octadecanoid pathwaycomprised of a cyclopentanone ring, cyclopentene ring, or other ketonemay include an alkane chain or an alkene chain, or may include adifferent hydrocarbon chain and may include a carboxylic acid side chainof different lengths.

Shown below is the structure for Methyl Jasmonate (MeJA) (from NationalCenter for Biotechnology Information (2021). PubChem Compound Summaryfor CID 5281929, Methyl jasmonate).

Shown below is the structure for methyl dihydrojasmonate (MDJ) (NationalCenter for Biotechnology Information (2021). PubChem Compound Summaryfor CID 102861, Methyl dihydroasmonate).

Shown below is the structure for cis-jasmone (CJ) (National Center forBiotechnology Information (2021). PubChem Compound Summary for CID1549018, Jasmone).

All jasmonates and even jasmonate-like molecules, including (+)-cucurbicacid and tuberonic acid, share some similarities in their chemicalstructures, such as cyclopentanone rings. However specificjasmonate-type responses in plants may be structure dependent and basedon the presence of hydroxyl groups, methyl groups, hydrocarbon chains,carboxylic acid chains, or other functional groups, or may be dependenton the chirality of each jasmonate type compound, or may be dependent onthe compound's stereoisomerism, or may be dependent on the compound'sspatial isomerism, or otherwise dependent on the structure.

Prohydrojasmone (PDJ) is a synthetic derivative of jasmonic acidpreviously shown to increase anthocyanain and bring about the red colorin apples (BLUSH™). Methyl dihydrojasmonate is only producedendogenously in a few plants, thus its ability to function as anelicitor was previously unresearched. Additionally, jasmonatederivatives like cis-jasmone (CJ) may be used to elicit more specificresponses when applied exogenously in planta in comparison to thestandard jasmonate elicitors like JA and MeJA.

Secondary Metabolites

Secondary plant metabolites are compounds which are not required for thegrowth and reproduction of the organism, but provide some advantage tothe organism (bacteria, fungi, and plants) and may be required forsurvival. For example, a secondary metabolite may attract a pollinatorthrough color or scent, or provide defense from an invading bacterial,viral, or fungal species. They may confer protection from UV radiation,or an insect pest, or aid in wound healing. They are also responsiblefor the aromas and flavors of plants (which may deter predators). Theycan be classified based on their chemical structures. Example classes ofsecondary metabolites includes phenolics (tanins, coumarins, flavonoids,chromones and xanthones, stilbenes, lignans), alkaloids, saponins,terpenes, and cannabinoids.

Phenolics

Phenolic compounds are a large group of secondary metabolites,characterized by the presence of at least one phenol group, but may befurther grouped as simple phenolics, tannins, coumarins, flavonoids,chromones and xanthones, stilbenes, and lignans. They are an importantcomponent of the human diet and have numerous health benefits, includingfor example, as an antioxidant, antimicrobial, anticancer,anti-inflammatory, and anti-mutagenic. They may also be used in personalcare items, and as a food preservative (Kumar N, Goel N. Phenolic acids:Natural versatile molecules with promising therapeutic applications.Biotechnol Rep (Amst). 2019; 24; Lin D, et al. An Overview of PlantPhenolic Compounds and Their Importance in Human Nutrition andManagement of Type 2 Diabetes. Molecules. 2016; 21(10):1374.).

In some embodiments, application of the compositions disclosed hereinalter the production of a phenolic in a plant or plant part. In someembodiments, the phenolic is a simple phenolic, tannin, coumarin,flavonoid, chromone, xanthone, stilbene, or lignan.

Simple Phenolics

Simple phenolics are so named because they have a single benzene(aromatic) ring. Examples of simple phenolics include, but are notlimited to, phenolic acids, such as gallic acid, caffeic acid, ferulicacid, protocatechuic acid, coumaric acid, salicylic acid, sinapic acid,catechol, phloroglucinol, thymol, salicylaldehyde, eugenol, andhydroquinone. (Guy B. Kougan, et al., 6-Simple Phenols, Phenolic Acids,and Related Esters from the Medicinal Plants of Africa, Medicinal PlantResearch in Africa, 2013, Pages 225-249.).

Tannins

Tannins (sometimes called tannic acids) are polyphenols found in manyplants and plant parts such as seeds, bark, wood, leaves, and fruitskins. The phrase “tanning” as it relates to leather actually comes fromthe tannins extracted from oak trees used on animal hides. Tannin levelsare high in unripened fruits, and this discourages animals from eatingthe fruit until the seeds are ready for dispersal. In addition to fruit,tannins are also found in coffee, tea, wine, and beer. Tannins may beused for ink, dye, medicinal purposes, and personal care products. Forexample, witch hazel (derived from Hamamelis virginiana) is anastringent used for skin care and mouthwash. Some tannins haveantibacterial properties, for example the tannins in cranberries(Vaccinium macrocarpon) may help prevent urinary tract infections andstomach ulcers. Some tannins have also been shown to reduce LDLcholesterol.

Example tannins include, but are not limited to, gallotannin (commontannic acid), ellagitannins (such as corilagin, pedunculagin),epigallocatechin gallate, (−)-epicatechin gallate (ECG) (the main“tannin” in green tea), dehydroellagitannin, caffetannins,labiataetannins, and phlorotannins. Example plants that produce tanninsinclude, but art not limited to, Aleppo oak (Quercus infectoria),Chinese nutgall (Rhus chinensis), Caesalpinia spinosa, the Europeanchestnut tree (principally Castanea sativa), American chestnut oak (Q.montana) quebracho (Schinopsis), mangrove (various genera and species),wattle (Acacia), strawberry, pomegranates, cranberries, blueberries,nuts, herbs (such as cloves, tarragon, cumin, thyme, vanilla, andcinnamon), grapevine, cacao, and legumes.

In some embodiments, application of the compositions disclosed hereinalter the production of a tannin in a plant or plant part. In someembodiments, the tannin is a gallotannin, an ellagitannin,epigallocatechin gallate, (−)-epicatechin gallate (ECG),dehydroellagitannin, a caffetannin, a labiataetannin, or a phlorotannin.

Coumarins are a family of benzopyrones (fused benzene and α-pyronerings). Some coumarins have been shown to be effective at improvingmemory, reducing inflammation, anticoagulant, and fighting cancer. Theyare also used in perfumes, cosmetics, and additives (for example as anaroma enhancer).

Examples of coumarins include, but are not limited to, simple coumarins(coumarin, esculetin, ammoresinol, ostruthin, osthole, novobicocin,coumermycin, umbelliferone, fraxidin, phellodenol), furanocoumarins(imperatorin, psoralen, bergapten, methoxsalen, marmalde, marmelosin),dihydrofuranocoumarins (anthogenol, felamidin, marmesin, rutaretin),pyranocoumarins (grandivittin, agasyllin, aegelinol benzoate,xantheyletin, inophyllum A, B, C, E, P, G1, and G2, calanolide A, B, andF, dihydrocalanolide A and B, pseudocordatolide), phenylcoumarins(isodispar B, dispardiol B, mammea A/AB cyclo E, mammea A/ABdioxalanocyclo F, disparinol D, disparpropylinol B), bicoumarins(dicoumarol), and daphnetin. Example plants that produce coumarinsinclude, but are not limited to, shankhpushpi (C. pluricaulis), Scopoliagenus, Magnolia, coumarou, seeds of Dipteryx odorata (Coumarounaodorata), Fabaceae, Apiaceae, Rutaceae, Asteraceae, Oleaceae, Moraceae,and Thymelaeaceae. Additional examples of coumarins and plants thatproduce coumarins can be found in, for example, Matos M. et al.,Coumarins—An Important Class of Phytochemicals, 2015.

Flavonoids

Flavonoids represent a large family of secondary metabolites having thegeneral structure of two phenyl rings and a heterocyclic ring. Nearly6000 structures have been identified in plants (Hichri I, et al., Recentadvances in the transcriptional regulation of the flavonoid biosyntheticpathway. J Exp Bot. 2011 May; 62(8):2465-83). They have diversebiological roles, including for example, antioxidant, anti-inflammatory,and antimicrobial. As antioxidants, some flavonoids are used in healthsupplements.

Flavonoids can be sub grouped into flavones (i.e., apigenin, tangeretin,baicalein, rpoifolin), isoflavones (i.e., genistin, genistein, daidzein,glycitein, daidzin), flavonols (also known as catechins) (i.e.,quercetin, myricetin, rutin, morin, kaempferol), flavonones (i.e.,hespertin, naringin, naringenin, eriodictyol, hesperidin), anthocyanins(i.e., cyanidin, malvidin, delphinidin, peonidin), and chalcones (i.e.,phloretin, arbutin, phlioridzin, chalconaringenin).

Some of the most well studies flavonoids include the flavonolskaempferol, quercetin, myricetin, and fisetin. Quercetin has a bitterflavor and is present in a variety of plants and food, for example,capers, buckwheat, radish, dill, cilantro, fennel, red onion, radicchio,watercress, kale, chokeberry, cranberry, black plums, lingonberry, redwine, and honey. Myricetin is found in, for example, tomatoes, oranges,nuts, berries, grapes, and tea.

It is highly addictive, and may act as either astimulant or a sedative depending on the dose. It has been shown toaffect heart rate, blood pressure, and insulin production. It also mayelevate mood, increase alertness, memory, and concentration, anddecrease anxiety.

Caffeine

Caffeine is an alkaloid most well-known for its presence in Camelliasinensis (tea), Coffea spp. (coffee), and Theobroma cacao (chocolate,cocoa) but it is also present in Cola spp. (kola nut, ‘cola’ as appliedto carbonated soft drinks), Ilex paraguariensis (yerba mate), guaranaberries, guayusa, and Ilex vomitoria (yaupon holly). Caffeine is presentin a number of beverages and some food products and when consumed,stimulates the central nervous system.

Vinca Alkaloids

Saponins

Saponins are amphipathic in nature, making them soluble in both fat andwater. Their foaming properties when mixed with water makes them usefulin soaps. Their name is actually derived from the soapwort plant, whichwas used in making soap, but they are widespread among plants. Some aretoxic to ingest, while others have health benefits and therapeutic use.Still others are used in food compositions and personal care items.

Examples of saponins include, but are not limited to, soyasaponins,found in legumes (Shi J, Arunasalam K, Yeung D, Kakuda Y, Mittal G,Jiang Y.

In some embodiments, application of the compositions disclosed hereinalter the production of a saponin in a plant or plant part.

Cannabinoids

Cannabinoids are a class of diverse chemical compounds that activatecannabinoid receptors. Cannabinoids produced by plants are calledphytocannabinoids, a.k.a., natural cannabinoids, herbal cannabinoids,and classical cannabinoids. Cannabinoids are the most studied group ofsecondary metabolites in Cannabis. Recent research however has nowidentified compounds in other plants, for example, clove, black pepper,echinacea, broccoli, ginseng, and carrots, that interact directly withcannabinoid receptors (Gertsch J, Pertwee R G, Di Marzo V.Phytocannabinoids beyond the Cannabis plant—do they exist? Br JPharmacol. 2010; 160(3):523-529).

Biosynthetic pathway of cannabinoids has been studied. See Meijer et al.I, II, III, and IV (I: 2003, Genetics, 163:335-346; II: 2005, Euphytica,145:189-198; III: 2009, Euphytica, 165:293-311; and IV: 2009, Euphytica,168:95-112), each of which is herein incorporated by reference in itsentirety for all purposes. According to the current model, phenolicprecursors such as geranyl pyrophosphate (GPP) and polyketide,olivetolic acid (OA) are condensed by geranyl pyrophosphate olivetolategeranyltransferase (GOT) to form Cannabigerol acid (CBGA).Alternatively, GPP and divarine acid are condensed by GOT to formCannabigerovarinic acid (CBGVA). CBGA or CBGAV is transformed to (1) CBCby CBC synthase or CBCV by CBCV synthase; (2) THC by THC synthase orTHCV by THCV synthase; or (3) CBD by CBD synthase or CBDV by CBDVsynthase. The genes coding for THC synthase and CBD synthase are foundon the same B locus. Thus Cannabis plants can be categorized intoTHC-CBD chemotypes based on the state of the B locus B_(T)/B_(T) (THCproducing, chemotype I), B_(D)/B_(D) (CBD producing, chemotype III), andB_(T)/B_(D) (producing both THC and CBD, chemotype II). Additionalinformation on the genetic regulation of cannabinoids can be found inMeijer et al. I, II, III, and IV (I: 2003, Genetics, 163:335-346; II:2005, Euphytica, 145:189-198; III: 2009, Euphytica, 165:293-311; and IV:2009, Euphytica, 168:95-112).

More details of cannabinoids synthesis and the properties and uses ofthese cannabinoids are described in Russo (2011, Taming THC: potentialCannabis synergy and phytocannabinoid-terpenoid entourage effects,British Journal of Pharmacology, 163:1344-1364), Russo et al. (2006, Atale of two cannabinoids: the therapeutic rationale for combiningtetrahydrocannabinol and cannabidiol, Medical Hypothesis, 2006,66:234-246), Celia et al. (Impact of cannabidiol on the acute memory andpsychotomimetic effects of smoked Cannabis: naturalistic study, TheBritish Journal of Psychiatry, 201, 197:285-290), de Mello Schier etal., (Cannabidiol, a Cannabis sativa constituent, as an anxiolytic drug,Rev. Bras.

At least 85 different cannabinoids have been isolated from the Cannabisplant (El-Alfy et al., 2010, “Antidepressant-like effect ofdelta-9-tetrahydrocannabinol and other cannabinoids isolated fromCannabis sativa L”, Pharmacology Biochemistry and Behavior 95 (4):434-42; Brenneisen, supra). Typical cannabinoids isolated from Cannabisplants include, but are not limited to, include, but are not limited to,Δ⁹-Tetrahydrocannabinol (Δ⁹-THC), Δ⁸-Tetrahydrocannabinol (Δ⁸-THC),Cannabichromene (CBC), Cannabicyclol (CBL), Cannabidiol (CBD),Cannabielsoin (CBE), Cannabigerol (CBG), Cannabinidiol (CBND),Cannabinol (CBN), Cannabitriol (CBT), and their propyl homologs,including, but are not limited to cannabidivarin (CBDV),Δ⁹-Tetrahydrocannabivarin (THCV), cannabichromevarin (CBCV), andcannabigerovarin (CBGV). See Holley et al. (Constituents of Cannabissativa L. XI Cannabidiol and cannabichromene in samples of knowngeographical origin, J. Pharm. Sci. 64:892-894, 1975) and De Zeeuw etal. (Cannabinoids with a propyl side chain in Cannabis, Occurrence andchromatographic behavior, Science 175:778-779), each of which is hereinincorporated by reference in its entirety for all purposes. Non-THCcannabinoids can be collectively referred to as “CBs”, wherein CBs canbe one of THCV, CBDV, CBGV, CBCV, CBD, CBC, CBE, CBG, CBN, CBND, and CBTcannabinoids.

Most cannabinoids exist in two forms, as acids and in neutral(decarboxylated) forms. The acid form is designated by an “A” at the endof its acronym (i.e., THCA). The phytocannabinoids are synthesized inthe plant as acid forms, and while some decarboxylation does occur inthe plant, it increases significantly post-harvest and the kineticsincrease at high temperatures. (Sanchez and Verpoorte 2008). Thebiologically active forms for human consumption are the neutral forms.Decarboxylation is usually achieved by thorough drying of the plantmaterial followed by heating it, often by either combustion,vaporization, or heating or baking in an oven. Unless otherwise noted,references to cannabinoids in a plant include both the acidic anddecarboxylated versions (e.g., CBD and CBDA).

Tetrahydrocannabinol (THC)

Known as delta-9-tetrahydrocannabinol (Δ9-THC), THC is the principalpsychoactive constituent (or cannabinoid) of the Cannabis plant. Theinitially synthesized and accumulated form in plant is THC acid (THCA).

THC has mild to moderate analgesic effects, and Cannabis can be used totreat pain by altering transmitter release on dorsal root ganglion ofthe spinal cord and in the periaqueductal gray. Other effects includerelaxation, alteration of visual, auditory, and olfactory senses,fatigue, and appetite stimulation. THC has marked antiemetic properties,and may also reduce aggression in certain subjects (Hoaken (2003).“Drugs of abuse and the elicitation of human aggressive behavior”.Addictive Behaviors 28: 1533-1554).

The pharmacological actions of THC result from its partial agonistactivity at the cannabinoid receptor CB₁, located mainly in the centralnervous system, and the CB₂ receptor, mainly expressed in cells of theimmune system (Pertwee, 2006, “The pharmacology of cannabinoid receptorsand their ligands: An overview”. International Journal of Obesity 30:S13-S18.) The psychoactive effects of THC are primarily mediated by itsactivation of CB1G-protein coupled receptors, which result in a decreasein the concentration of the second messenger molecule cAMP throughinhibition of adenylate cyclase (Elphick et al., 2001, “The neurobiologyand evolution of cannabinoid signaling”. Philosophical Transactions ofthe Royal Society B: Biological Sciences 356 (1407): 381-408.) It isalso suggested that THC has an anticholinesterase action which mayimplicate it as a potential treatment for Alzheimer's and Myasthenia(Eubanks et al., 2006, “A Molecular Link Between the Active Component ofMarijuana and Alzheimer's Disease Pathology”. Molecular Pharmaceutics 3(6): 773-7.)

THC occurs mainly as tetrahydrocannabinolic acid (THCA, 2-COOH-THC).Geranyl pyrophosphate and olivetolic acid react, catalyzed by an enzymeto produce cannabigerolic acid, which is cyclized by the enzyme THC acidsynthase to give THCA. Over time, or when heated, THCA is decarboxylatedproducing THC. The pathway for THCA biosynthesis is similar to thatwhich produces the bitter acid humulone in hops. See Fellermeier et al.,(1998, “Prenylation of olivetolate by a hemp transferase yieldscannabigerolic acid, the precursor of tetrahydrocannabinol”. FEBSLetters 427 (2): 283-5); de Meijer et al. I, II, III, and IV (I: 2003,Genetics, 163:335-346; II: 2005, Euphytica, 145:189-198; III: 2009,Euphytica, 165:293-311; and IV: 2009, Euphytica, 168:95-112.)

Non-limiting examples of THC variants include:

Cannabidiol (CBD)

CBD is a cannabinoid found in Cannabis. Cannabidiol has displayedsedative effects in animal tests (Pickens, 1981, “Sedative activity ofCannabis in relation to its delta'-trans-tetrahydrocannabinol andcannabidiol content”. Br. J. Pharmacol. 72 (4): 649-56). Some research,however, indicates that CBD can increase alertness, and attenuate thememory-impairing effect of THC. (Nicholson et al., June 2004, “Effect ofDelta-9-tetrahydrocannabinol and cannabidiol on nocturnal sleep andearly-morning behavior in young adults” J Clin Psychopharmacol 24 (3):305-13; Morgan et al., 2010, “Impact of cannabidiol on the acute memoryand psychotomimetic effects of smoked Cannabis: naturalistic study, TheBritish Journal of Psychiatry, 197:258-290). It may decrease the rate ofTHC clearance from the body, perhaps by interfering with the metabolismof THC in the liver. Medically, it has been shown to relieve convulsion,inflammation, anxiety, and nausea, as well as inhibit cancer cell growth(Mechoulam, et al., 2007, “Cannabidiol—recent advances”. Chemistry &Biodiversity 4 (8): 1678-1692.) Recent studies have shown cannabidiol tobe as effective as atypical antipsychotics in treating schizophrenia(Zuardi et al., 2006, “Cannabidiol, a Cannabis sativa constituent, as anantipsychotic drug” Braz. J. Med. Biol. Res. 39 (4): 421-429.). Studieshave also shown that it may relieve symptoms of dystonia (Consroe, 1986,“Open label evaluation of cannabidiol in dystonic movement disorders”.The International journal of neuroscience 30 (4): 277-282). CBD reducesgrowth of aggressive human breast cancer cells in vitro and reducestheir invasiveness (McAllister et al., 2007, “Cannabidiol as a novelinhibitor of Id-1 gene expression in aggressive breast cancer cells”.Mol. Cancer Ther. 6 (11): 2921-7.)

Cannabidiol has shown to decrease activity of the limbic system (deSouza Crippa et al., “Effects of Cannabidiol (CBD) on Regional CerebralBlood Flow”. Neuropsychopharmacology 29 (2): 417-426.) and to decreasesocial isolation induced by THC (Malon et al., “Cannabidiol reverses thereduction in social interaction produced by low doseΔ9-tetrahydrocannabinol in rats”. Pharmacology Biochemistry and Behavior93 (2): 91-96.) It's also shown that Cannabidiol reduces anxiety insocial anxiety disorder (Bergamaschi et al., 2003, “Cannabidiol Reducesthe Anxiety Induced by Simulated Public Speaking in Treatment-NaïveSocial Phobia Patients”. Neuropsychopharmacology 36 (6): 1219-1226).Cannabidiol has also been shown as being effective in treating an oftendrug-induced set of neurological movement disorders known as dystonia(Snider et al., 1985, “Beneficial and Adverse Effects of Cannabidiol ina Parkinson Patient with Sinemet-Induced Dystonic Dyskinesia”.Neurology, (Suppl 1): 201.) Morgan et al. reported that strains ofCannabis which contained higher concentrations of Cannabidiol did notproduce short-term memory impairment vs. strains which contained similarconcentrations of THC (2010, “Impact of cannabidiol on the acute memoryand psychotomimetic effects of smoked Cannabis: naturalistic study:naturalistic study [corrected.”]. British Journal of Psychiatry 197 (4):285-90.)

Cannabidiol acts as an indirect antagonist of cannabinoid agonists. CBDis an antagonist at the putative new cannabinoid receptor, GPR55.Cannabidiol has also been shown to act as a 5-HT1A receptor agonist, anaction which is involved in its antidepressant, anxiolytic, andneuroprotective effects. Cannabidiol is also an allosteric modulator atthe Mu and Delta opioid receptor sites.

Cannabis produces CBD-carboxylic acid through the same metabolic pathwayas THC, until the last step, where CBDA synthase performs catalysisinstead of THCA synthase. See Marks et al. (2009, “Identification ofcandidate genes affecting Δ9-tetrahydrocannabinol biosynthesis inCannabis sativa”. Journal of Experimental Botany 60 (13): 3715-3726.)and Meijer et al. I, II, III, and IV.

Non-limiting examples of CBD variants include:

Cannabigerol (CBG)

CBG is a non-psychoactive cannabinoid found in the Cannabis genus ofplants. Cannabigerol is found in higher concentrations in hemp ratherthan in varieties of Cannabis cultivated for high THC content and theircorresponding psychoactive properties. Cannabigerol has been found toact as a high affinity α2-adrenergic receptor agonist, moderate affinity5-HT1A receptor antagonist, and low affinity CB₁ receptor antagonist. Italso binds to the CB₂ receptor. Cannabigerol has been shown to relieveintraocular pressure, which may be of benefit in the treatment ofglaucoma (Craig et al. 1984, “Intraocular pressure, ocular toxicity andneurotoxicity after administration of cannabinol or cannabigerol”Experimental eye research 39 (3):251-259). Cannabigerol has also beenshown to reduce depression in animal models (U.S. Pat. No. 8,481,085).

Non-limiting examples of CBG variants include:

Cannabinol (CBN)

CBN is a psychoactive substance cannabinoid found in Cannabis sativa andCannabis indica/afghanica. It is also a metabolite oftetrahydrocannabinol (THC). CBN acts as a weak agonist of the CB1 andCB2 receptors, with lower affinity in comparison to THC.

Non-limiting examples of CBN variants include:

Cannabichromene (CBC)

CBC bears structural similarity to the other natural cannabinoids,including tetrahydrocannabinol, tetrahydrocannabivarin, cannabidiol, andcannabinol, among others. Evidence has suggested that it may play a rolein the anti-inflammatory and anti-viral effects of Cannabis, and maycontribute to the overall analgesic effects of Cannabis.

Non-limiting examples of CBC variants include:

Cannabivarin (CBV)

Cannabivarin, also known as cannabivarol or CBV, is a non-psychoactivecannabinoid found in minor amounts in the hemp plant Cannabis sativa. Itis an analog of cannabinol (CBN) with the side chain shortened by twomethylene bridges (—CH2-). CBV is an oxidation product oftetrahydrocannabivarin (THCV, THV).

Cannabidivarin (CBDV)

CBDV is a non-psychoactive cannabinoid found in Cannabis. It is ahomolog of cannabidiol (CBD), with the side-chain shortened by twomethylene bridges (CH2 units). Cannabidivarin has been found reduce thenumber and severity of seizures in animal models (U.S. Pat. No.9,125,859). Plants with relatively high levels of CBDV have beenreported in feral populations of C. indica (=C. sativa ssp. indica var.kafiristanica) from northwest India, and in hashish from Nepal.

Tetrahydrocannabivarin (THCV, THV)

THCV, or THV is a homologue of tetrahydrocannabinol (THC) having apropyl (3-carbon) side chain. This terpeno-phenolic compound is foundnaturally in Cannabis, sometimes in significant amounts. Plants withelevated levels of propyl cannabinoids (including THCV) have been foundin populations of Cannabis sativa L. ssp. indica (=Cannabis indica Lam.)from China, India, Nepal, Thailand, Afghanistan, and Pakistan, as wellas southern and western Africa. THCV has been shown to be a CB1 receptorantagonist, i.e., it blocks the effects of THC. Tetrahydrocannabinol hasbeen shown to increase metabolism, help weight loss and lowercholesterol in animal models.

Cannabicyclol (CBL)

Cannabicyclol (CBL) is a non-psychotomimetic cannabinoid found in theCannabis species. CBL is a degradative product like cannabinol. Lightconverts cannabichromene to CBL.

Non-limiting examples of CBL variants include:

Cannabitriol (CBT)

CBT occurs in small amounts and is not present in all Cannabisvarieties. It has a structure similar to THC, but it is a relativelynewly discovered cannabinoid and thus has not been extensively studied.

Non-limiting examples of CBT variants include:

Medical uses for cannabinoids are well known in the art. See forexample, Consroe, 1986, The International journal of neuroscience 30(4): 277-282, Colasanti et al, Exp. Eye Res. 30:251-259, 1984, Gen.Pharmac. 15:479-484, 1984, Craig et al. 1984, Experimental eye research39 (3):251-259, U.S. PAT 6,630,507, Snider et al., 1985, “Beneficial andAdverse Effects of Cannabidiol in a Parkinson Patient withSinemet-Induced Dystonic Dyskinesia”.

In some embodiments, application of the compositions disclosed hereinalter the production of a cannabinoid in a plant or plant part. In someembodiments, the cannabinoid is Δ⁹-Tetrahydrocannabinol (Δ⁹-THC),Δ⁸-Tetrahydrocannabinol (Δ⁸-THC), Cannabichromene (CBC), Cannabicyclol(CBL), Cannabidiol (CBD), Cannabielsoin (CBE), Cannabigerol (CBG),Cannabinidiol (CBND), Cannabinol (CBN), Cannabitriol (CBT),cannabidivarin (CBDV), Δ⁹-Tetrahydrocannabivarin (THCV),cannabichromevarin (CBCV), or cannabigerovarin (CBGV).

In some embodiments, the disclosure teaches a method for producing acannabinoid, the method comprising: a) applying an effective amount ofmethyl dihydrojasmonate to a Cannabis spp. plant, wherein said plantcomprises an inflorescence; b) extracting a cannabinoid from saidCannabis sp. plant by either: i) contacting a part of the plant with asolvent, causing the cannabinoid to separate from the plant part; and/orii) exposing a part of the plant to heat, causing the cannabinoid toseparate from the plant part; and collecting said separated cannabinoid,thereby producing a cannabinoid. In some aspects, the method furthercomprises the step of admixing the cannabinoid with a carrier oil. Insome aspects, the method further comprises the step of admixing thecannabinoid with a terpene.

All cannabinoids in their acid forms (those ending in “-A”) can beconverted to their non-acidic forms through a process calleddecarboxylation. Decarboxylation is usually achieved by thorough dryingof the plant material followed by heating it, often by eithercombustion, vaporization, or heating or baking in an oven. Cannabinoidcompositions can similarly be decarboxylated by being exposed to heat.

In order to find the total amount of cannabinoids in a sample (e.g.,total amount of active non-acidic cannabinoid), the total measuredcontent of acid cannabinoid variants forms should be adjusted to accountfor the loss of the carboxyl group. In some embodiments, this adjustmentcan be made by multiplying the molar content of the acidic cannabinoidforms by the molecular weight of the corresponding decarboxylatedcannabinoid. Other shorthand conversions are also available for quicklyconverting acidic cannabinoid content to active cannabinoid content.

For example, in some embodiments, THCA can be converted to active THCusing the formula: THCA×0.877=THC. When using this approach, the maximumTHC for the sample is: THCmax=(THCA×0.877)+THC. This method has beenvalidated according to the principles of the International Conference onHarmonization. Similarly, CBDA can be converted to active CBD and theyield is determined using the yield formula: CBDA×0.877=CBD. Also, themaximum amount of CBD yielded, i.e., max CBD for the sample is:CBDmax=(CBDA×0.877)+CBD. Additionally, CBGA can be converted to activeCBG by multiplying CBGA by 0.878 (CBGmax=(CBGA×0.878)+CBG). THCVA andCBDVA can be converted to THCV and CBDV, respectively by multiplyingtheir acidic contents by 0.8668 (THCVmax=(THCVA×0.8668)+THCV;CBDVmax=(CBDVA×0.8668)+CBDV). CBGVA can be converted to CBGV bymultiplying CBGVA by 0.8676 (CBGVmax=(CBGVA×0.8676)+CBGV)

Terpenes

Terpenes are a large and diverse class of organic compounds, produced bya variety of plants. They are often strong smelling and thus may havehad a protective function. Terpenes are derived biosynthetically fromunits of isoprene, which has the molecular formula C₅H₈. The basicmolecular formulae of terpenes are multiples of that, (C₅H₈)_(n) where nis the number of linked isoprene units. The isoprene units may be linkedtogether “head to tail” to form linear chains or they may be arranged toform rings. Non-limiting examples of terpenes include Hemiterpenes,Monoterpenes, Sesquiterpenes, Diterpenes, Sesterterpenes, Triterpenes,Sesquarterpenes, Tetraterpenes, Polyterpenes, and Norisoprenoids.

Terpenoids, a.k.a. isoprenoids, are a large and diverse class ofnaturally occurring organic chemicals similar to terpenes, derived fromfive-carbon isoprene units assembled and modified in thousands of ways.Most are multicyclic structures that differ from one another not only infunctional groups but also in their basic carbon skeletons. Plantterpenoids are used extensively for their aromatic qualities. They playa role in traditional herbal remedies and are under investigation forantibacterial, antineoplastic, and other pharmaceutical functions. Theterpene Linalool for example, has been found to have anti-convulsantproperties (Elisabetsky et al., Phytomedicine, May 6(2):107-13 1999).Well-known terpenoids include citral, menthol, camphor, salvinorin A inthe plant Salvia divinorum, and the cannabinoids found in Cannabis.Non-limiting examples of terpenoids include, Hemiterpenoids, 1 isopreneunit (5 carbons); Monoterpenoids, 2 isoprene units (10C);Sesquiterpenoids, 3 isoprene units (15C); Diterpenoids, 4 isoprene units(20C) (e.g., ginkgolides); Sesterterpenoids, 5 isoprene units (25C);Triterpenoids, 6 isoprene units (30C) (e.g., sterols); Tetraterpenoids,8 isoprene units (40C) (e.g., carotenoids); and Polyterpenoid with alarger number of isoprene units.

Terpenoids are mainly synthesized in two metabolic pathways: mevalonicacid pathway (a.k.a. HMG-CoA reductase pathway, which takes place in thecytosol) and MEP/DOXP pathway (a.k.a. The 2-C-methyl-D-erythritol4-phosphate/1-deoxy-D-xylulose 5-phosphate pathway, non-mevalonatepathway, or mevalonic acid-independent pathway, which takes place inplastids). Geranyl pyrophosphate (GPP), which is used by Cannabis plantsto produce cannabinoids, is formed by condensation of dimethylallylpyrophosphate (DMAPP) and isopentenyl pyrophosphate (IPP) via thecatalysis of GPP synthase. Alternatively, DMAPP and IPP are ligated byFPP synthase to produce farnesyl pyrophosphate (FPP), which can be usedto produce sesquiterpenoids. Geranyl pyrophosphate (GPP) can also beconverted into monoterpenoids by limonene synthase.

In some embodiments, the production of terpenes and terpenoids derivedfrom isoprene units, including acyclic, monocyclic, bicyclic, tricyclic,tetracyclic, pentacyclic, hexacyclic, heptacyclic, and octacycliccyclisations of hemiterpenes, monoterpenes, sesquiterpenes, diterpenes,sesterterpenes, triterpenes, sesquarterpenes, tetraterpenes, andpolyterpenes are manipulated independently of each other. In someembodiments, the production of terpenes and terpenoids derived fromisoprene units, including acyclic, monocyclic, bicyclic, tricyclic,tetracyclic, pentacyclic, hexacyclic, heptacyclic, and octacycliccyclisations of hemiterpenes, monoterpenes, sesquiterpenes, diterpenes,sesterterpenes, triterpenes, sesquarterpenes, tetraterpenes, andpolyterpenes are manipulated relative to each other.

Limonene

D-Limonene is a monoterpenoid that is widely distributed in nature andoften associated with citrus. It has strong anxiolytic properties inboth mice and humans, apparently increasing serotonin and dopamine inmouse brain. D-limonene has potent anti-depressant activity wheninhaled. It is also under investigation for a variety of differentcancer treatments, with some focus on its hepatic metabolite, perillicacid. There is evidence for activity in the treatment of dermatophytesand gastro-oesophageal reflux, as well as having general radicalscavenging properties (Russo 2011, Taming THC: potential Cannabissynergy and phytocannabinoid-terpenoid entourage effects, BritishJournal of Pharmacology, 163:1344-1364).

Myrcene

β-Myrcene is a monoterpenoid also found in Cannabis, and has a varietyof pharmacological effects. It is often associated with a sweet fruitlike taste. It reduces inflammation, aids sleep, and blocks hepaticcarcinogenesis, as well as acting as an analgesic and muscle relaxant inmice. When β-myrcene is combined with Δ9-THC it could intensify thesedative effects of Δ9-THC, causing the well-known “couch-lock” effectthat some Cannabis users experience (Russo 2011, Taming THC: potentialCannabis synergy and phytocannabinoid-terpenoid entourage effects,British Journal of Pharmacology, 163:1344-1364).

Linalool

Linalool is a monoterpenoid with very well-known anxiolytic effects. Itis often associated with lavender, and frequented used in aromatherapyfor its sedative impact. It acts as a local anaesthetic and helps toprevent scarring from burns, is anti-nociceptive in mice, and showsantiglutamatergic and anticonvulsant activity. Its effects on glutamateand GABA neurotransmitter systems are credited with giving it itssedative, anxiolytic, and anticonvulsant activities (Russo 2011, TamingTHC: potential Cannabis synergy and phytocannabinoid-terpenoid entourageeffects, British Journal of Pharmacology, 163:1344-1364). Exemplaryplants that produce linalool are shown below in Table 1.

α-Pinene

α-Pinene is a monoterpene common in nature, also with a plethora ofeffects on mammals and humans. It acts as an acetylcholinesteraseinhibitor which aids memory and counteracts the short-term memory lossassociated with Δ₉-THC intoxication, is an effective antibiotic agent,and shows some activity against MRSA. In addition, α-pinene is abronchodilator in humans and has anti-inflammatory properties via theprostaglandin E-1 pathway (Russo 2011, Taming THC: potential Cannabissynergy and phytocannabinoid-terpenoid entourage effects, BritishJournal of Pharmacology, 163:1344-1364). Exemplary plants that produceα-pinene are shown below in Table 1.

β-Caryophyllene

β-Caryophyllene is often the most predominant sesquiterpenoid inCannabis. It is less volatile than the monoterpenoids, thus it is foundin higher concentrations in material that has been processed by heat toaid in decarboxylation. It is very interesting in that it is a selectivefull agonist at the CB₂ receptor, which makes it the onlyphytocannabinoid found outside the Cannabis genus. In addition, it hasanti-inflammatory and gastric cytoprotective properties, and may evenhave anti-malarial activity. Exemplary plants that produceβ-caryophyllene are shown below in Table 1.

Caryophyllene Oxide

Caryophyllene oxide is another sesquiterpenoid found in Cannabis, whichhas antifungal and anti-platelet aggregation properties. As an aside, itis also the molecule that drug-sniffing dogs are trained to find (Russo2011, Taming THC: potential Cannabis synergy andphytocannabinoid-terpenoid entourage effects, British Journal ofPharmacology, 163:1344-1364). Exemplary plants that producecaryophyllene oxide are shown below in Table 1.

Nerolidol

Nerolidol is a sesquiterpene that is often found in citrus peels thatexhibits a range of interesting properties. It acts as a sedative,inhibits fungal growth, and has potent anti-malarial and antileishmanialactivity. It also alleviated colon adenomas in rats (Russo 2011, TamingTHC: potential Cannabis synergy and phytocannabinoid-terpenoid entourageeffects, British Journal of Pharmacology, 163:1344-1364). Phytol is aditerpene often found in Cannabis extracts. It is a degradation productof chlorophyll and tocopherol. It increases GABA expression andtherefore could be responsible the relaxing effects of green tea andwild lettuce. It also prevents vitamin-A induced teratogenesis byblocking the conversion of retinol to its dangerous metabolite,all-trans-retinoic acid (Russo 2011, Taming THC: potential Cannabissynergy and phytocannabinoid-terpenoid entourage effects, BritishJournal of Pharmacology, 163:1344-1364).

Example Plants that Produce Secondary Metabolites

Cannabis

Cannabis, more commonly known as marijuana, is a genus of floweringplants that includes at least three species, Cannabis sativa, Cannabisindica, and Cannabis ruderalis as determined by plant phenotypes andsecondary metabolite profiles. In practice however, Cannabisnomenclature is often used incorrectly or interchangeably. Cannabisliterature can be found referring to all Cannabis varieties as “sativas”or all cannabinoid producing plants as “indicas”. Indeed, thepromiscuous crosses of indoor Cannabis breeding programs have made itdifficult to distinguish varieties, with most Cannabis being sold in theUnited States having features of both sativa and indica species. Thepresent disclosure provides for Cannabis sp. (species) or Cannabis spp.(species pluralis), which comprises Cannabis sativa, Cannabis indica,and Cannabis ruderalis, as well as hybrids and variants thereof.

The profile of secondary metabolites in Cannabis plants can be theprimary determinant of the crop's value. In hemp crops, low-THCvarieties are not only mandated by law but coveted by consumers andcultivators. Hemp crops are generally utilized for their secondarymetabolites produce in planta in flower organs and other aerial tissues,which are extracted and refined using various techniques and solventssuch as lipid and hydrocarbon extractions. In high-THC varieties, whichare colloquially known as “marijuana”, less emphasis is placed on thevariety of secondary metabolites and greater emphasis is placed on theconcentration of the cannabinoids THCA (tetrahydrocannabinol acid) andits derivatives and/or the concentration of flavor and scent moleculeslike terpenes. In both instances, primary value of Cannabis crops hasbeen determined by the concentration of the secondary metabolites knownas cannabinoids and terpenes or terpenoids. Cannabis also producesflavonoids, steroids, alkaloids, phenols, and amides.

Cannabis plants produce a unique family of terpeno-phenolic compoundscalled cannabinoids. Cannabinoids, terpenoids, and other compounds aresecreted by glandular trichomes that occur most abundantly on the floralcalyxes and bracts of female plants. As a drug it usually comes in theform of dried flower buds (marijuana), resin (hashish), or variousextracts collectively known as hashish oil. There are at least 483identifiable chemical constituents known to exist in the Cannabis plant(Rudolf Brenneisen, 2007, Chemistry and Analysis of Phytocannabinoids(cannabinoids produced produced by Cannabis) and other CannabisConstituents, In Marijuana and the Cannabinoids, ElSohly, ed.;incorporated herein by reference) and at least 85 different cannabinoidshave been isolated from the plant (El-Alfy, Abir T, et al., 2010,“Antidepressant-like effect of delta-9-tetrahydrocannabinol and othercannabinoids isolated from Cannabis sativa L”, Pharmacology Biochemistryand Behavior 95 (4): 434-42; incorporated herein by reference). The twocannabinoids usually produced in greatest abundance are cannabidiol(CBD) and/or Δ⁹-tetrahydrocannabinol (THC). THC is psychoactive whileCBD is not. See, ElSohly, ed. (Marijuana and the Cannabinoids, HumanaPress Inc., 321 papers, 2007), which is incorporated herein by referencein its entirety, for a detailed description and literature review on thecannabinoids found in marijuana.

Some of the secondary metabolites produced include, but are not limitedto, pentyl, propyl, C-4, C-1 and monomethylether constituents ofcannabinoid families, including but not limited to acidic and neutralforms of the cannabigerol, cannabichromene, cannabidiol,delta-9-tetrahydrocannabinol, delta-8-tetrahydrocannabinol,cannabielsoin, cannabinol and cannabinodiol cannabinoid classes; and,cis and trans terpenoids, including but not limited to myrcene,limonene, linalool, ocimene, beta-pinene, alpha-pinene,beta-caryophyllene, alpha-caryophyllene, delta-3-carene,gamma-bisabolene, alpha-farnesene, beta-fenchol, guajol, alpha-guaiene,terpinolene, beta-eudesmol, alpha-bergamotene, epi-alpha-bisabolol andcaryophyllene oxide.

In addition to cannabinoids, Cannabis also produces over 120 differentterpenes (Russo 2011, Taming THC: potential Cannabis synergy andphytocannabinoid-terpenoid entourage effects, British Journal ofPharmacology, 163:1344-1364). Within the context and verbiage of thisdocument the terms ‘terpenoid’ and ‘terpene’ are used interchangeably.Cannabinoids are odorless, so terpenoids are responsible for the uniqueodor of Cannabis, and each variety has a slightly different profile thatcan potentially be used as a tool for identification of differentvarieties or geographical origins of samples (Hillig 2004. “Achemotaxonomic analysis of terpenoid variation in Cannabis” BiochemSystem and Ecology 875-891). It also provides a unique and complexorganoleptic profile for each variety that is appreciated by both noviceusers and connoisseurs. In addition to many circulatory and musculareffects, some terpenes interact with neurological receptors. A fewterpenes produced by Cannabis plants also bind weakly to Cannabinoidreceptors. Some terpenes can alter the permeability of cell membranesand allow in either more or less THC, while other terpenes can affectserotonin and dopamine chemistry as neurotransmitters. Terpenoids arelipophilic, and can interact with lipid membranes, ion channels, avariety of different receptors (including both G-protein coupled odorantand neurotransmitter receptors), and enzymes. Some are capable ofabsorption through human skin and passing the blood brain barrier.

Generally speaking, terpenes are considered to be pharmacologicallyrelevant when present in concentrations of at least 0.05% in plantmaterial (Hazekamp and Fischedick 2010. “Metabolic fingerprinting ofCannabis sativa L., cannabinoids and terpenoids for chemotaxonomic anddrug standardization purposes” Phytochemistry 2058-73; Russo 2011,Taming THC: potential Cannabis synergy and phytocannabinoid-terpenoidentourage effects, British Journal of Pharmacology, 163:1344-1364).Thus, although there are an estimated 120 different terpenes, only a feware produced at high enough levels to be detectable, and fewer stillwhich are able to reach pharmacologically relevant levels.

Some of the most common terpenes in Cannabis include: terpinolene, alphaphelladrene, beta ocimene, carene, limonene, gamma terpinene, alphapinene, alpha terpinene, beta pinene, fenchol, camphene, alphaterpineol, alpha humulene, beta caryophyllene, linalool, cary oxide, andmyrcene. A survey of the terpene profiles of several Cannabis varietieshas found that these terpenes express at high enough levels so as tohave their own pharmacological effects and also to act in synergy withcannabinoids. Both experts and consumers believe that there arebiochemical and phenomenological differences between different varietiesof Cannabis, which are attributed to their unique relative cannabinoidand terpenoid ratios. This is known as the entourage effect and isgenerally considered to result in plants providing advantages over onlyusing the natural products that are isolated from them (Russo 2011,Taming THC: potential Cannabis synergy and phytocannabinoid-terpenoidentourage effects, British Journal of Pharmacology, 163:1344-1364).

These advantages include synergy with THC, the primary activeingredient, and also mitigation of side effects from THC (McPartland andRusso 2001 “Cannabis and Cannabis Extracts: Greater Than the Sum ofTheir Parts?” Hayworth Press). Terpenoids can be extracted from theplant material by steam distillation (giving you essential oil) orvaporization, however the yield varies greatly by plant tissue, type ofextraction, age of material, and other variables (McPartland and Russo2001 “Cannabis and Cannabis Extracts: Greater Than the Sum of TheirParts?” Hayworth Press). Typically the yield of terpenoids in Cannabisis less than 1% by weight on analysis; however it is thought that theymay comprise up to 10% of the trichome content. Monoterpenoids areespecially volatile, thus decreasing their yield relative tosesquiterpenoids (Russo 2011, Taming THC: potential Cannabis synergy andphytocannabinoid-terpenoid entourage effects, British Journal ofPharmacology, 163:1344-1364).

EXAMPLES Example 1: Application of MeJA to a High Fiber Hemp VarietyAlters the Metabolome

The efficacy and effectiveness of an eliciting composition and methodsof use to alter secondary metabolite production were tested in acontrolled environment with a commercial certified hemp varietal‘Bialobreszkie’ (Bija Hemp, Denver, Colo., USA). Notably,‘Bialobreszkie’ is a relatively low metabolite-producing hemp varietydue to its predominant use as a fiber and grain variety, with totalcannabinoid content generally far less than 10% by weight. This is incomparison with high metabolite-producing hemp varieties that typicallyyield greater than 10% by weight total cannabinoids.

A non-targeted semi-quantitative metabolomic analysis was conducted toprovide relative values for each detected analyte (i.e., compound)rather than absolute quantification, but with much greater detectionlimits than typical quantitative analysis provides. Additionally, thenon-targeted nature allows essentially every compound that is present inthe sample to be recorded and scored relative, providing a picture ofthe effect that each treatment has on the entire metabolome of the plantrather than only a snapshot of a few metabolites. This type of analysisprovides significantly greater analytical inference and provided data onthe influence of each treatment on irregular secondary metabolites thatare not traditionally reported in the Cannabis and hemp industrialtesting labs.

Methyl Jasmonate (MeJA) was the active eliciting ingredient used in thisexperiment, as previous research has demonstrated its ability tosignificantly alter metabolite production in planta and provided a basisfrom which to best determine the effect that timing and frequency had onplant metabolic response.

One hundred and forty-four (144) ‘Bialobreszkie’ variety hemp seeds weresurface sterilized in a 2% NaOCI solution for 5 minutes and primed for12 hours in a 1:30 aqueous solution of TRIBUS® Original (a commercialplant growth promoting bacterial consortia) contained in a 50 mLcentrifuge tube and placed on an orbital shaker at 80 rpm, then handsewn into two 72-cell trays filled with commercial coco coir (CannaGardening, NL). Of the 144 seeds, 112 germinated well and were selectedfor use in the trial. After two weeks of development in seedling trays,all 112 plants were transplanted into 4″ square plastic pots filled withpure coco coir media and watered-in with a 4-20-39 fertilizersupplemented with calcium nitrate, magnesium sulfate, and TRIBUS®beneficial bacteria at a standardized rate. At the time of transplant,all plants were transitioned into the flowering stage by manipulatingthe photoperiod to a 12-hour light/12-hour dark schedule per 24-hourday.

Plants were transplanted successively without regard to their size orphysical attributes on Apr. 20, 2019. The square pots were arranged inan 8×16 grid on a 4′×8′ black plastic bench under two×1000-watt DE-HPSlamps (Gavita International BV). Each pot was numbered in numericalorder, row by row. After all plants/pots were labeled, a researchrandomizer tool (randomizer.org) was used to randomly generate 8 groupswith 14 unique numbers in each group, ranging from 1-112.

Treatment groups differed only in the frequency and timing ofapplications. Chemical composition of the elicitor formula remainedidentical between all treatment groups and consisted of a 7.5 mM methyljasmonate (MeJA, technical grade, TCI America) active ingredient appliedin an aqueous spray consisting of reverse-osmosis purified water,supplemented only with 0.1% v/v polysorbate-20 (TWEEN®-20, reagentgrade, VWR) as an emulsifier to support oil-in-water stability. Thecontrol group did not receive any applications of any chemical.Treatment groups were defined as follows:

TABLE 2 Treatment groups Plant ID number Treatment T1 64, 103, 59, 14,82, 80, 18, One application every 7 days, 78, 93, 34, 95, 74, 20, 96starting with the first day of flowering T2 50, 9, 3, 35, 40, 11, 26,One application every 14 days 102, 62, 47, 45, 28, 56, starting with thefirst day of 29 flowering T3 99, 44, 6, 98, 87, 15, 19, One applicationevery 28 days 109, 88, 48, 16, 111, 1, 89 starting with the first day offlowering T4 51, 49, 68, 108, 41, 69, 86, Only one application, on thefirst 75, 5, 60, 83, 24, 70, 63 day of flowering T5 30, 85, 21, 42, 53,71, 52, Only one application, on the 30th 57, 37, 100, 104, 106, 31, dayof flowering 101 T6 46, 65, 84, 27, 81, 77, 36, Only one application, 72hours 92, 112, 32, 54, 13, 8, 17 prior to harvest T7 55, 97, 33, 2, 73,105, 43, Only one application, 24 hours 107, 7, 12, 39, 94, 23, 66 priorto harvest C 90, 79, 61, 10, 76, 67, 110, no applications at any point4, 91, 58, 22, 38, 25, 72

All plants receiving treatments were sprayed-to-drip with eachapplication to ensure sufficient coverage. Treatments were made to alltreatment plants during daylight hours but out of direct light. Plantswere temporarily removed from the growing bench for treatmentapplications in order to prevent overspray of the treatment onto otherplants in the experiment. In such instances, plants were returned to thegrowing bench immediately after the foliage had dried. Plants werecultivated under identical and typical growing conditions for 47 days,then whole plants were harvested successively and within one hour ofeach other, labeled with their corresponding plant number, and hungupside down in a well-ventilated room and allowed to dry. Loss ofsamples occurred either from plants dying during the experiment orinsufficient flower set. All other plants in the experiment wereapproximately the same size and had similar numbers and size of flowers.

Each of the 8 groups (7 treatment and 1 control) began the trial with 14plants. 109 of 112 samples were run in the assay. Due to the lossesnoted above, 12 samples were submitted from Treatment 1, 13 fromTreatment 4, and 13 from Treatment 5. All other groups had 14 samplesincluded in the assay.

Sample Preparation

Representative samples from each plant were taken after uniform moisturelevels were achieved throughout the entire population, labeled andbagged, and taken directly to the Proteomics and Metabolomics Facility(PMF) at Colorado State University (CSU) for metabolomic analysis.Samples were submitted as whole flower without removal of any leaf,stem, or seed and no trimming.

The sample prep at CSU included removal of large stems and seedmechanically. The very small required sample mass (0.1 g) eliminatesvariability that you would otherwise expect if stem, leaf, seed, etc wasincluded in a typical Cannabis assay, where much larger masses arerequired (+1.0 g), and seed/stem can significantly impact themeasurement.

Samples were submitted to CSU-PMF partially dried. Each sample wastapped to remove most of the seeds and retain only the chaff and leavesfor analysis. Stems were also removed. The samples were then placed inSterile 5 mL Transport Tubes with small beads and placed inside theBULLET BLENDER® STORM 5 to grind and homogenize samples. For UPLC-MSanalysis, 100 mg+/−1 mg of sample was weighed into a 2 mL clear glassautosampler vial and suspended with 1 mL of 80% LCMS-grade methanol inwater. The samples were then shaken for 2 hours at 4° C. and sonicatedfor 30 minutes in a cold bath. The samples were shaken for an additionalhour at 4° C. then centrifuged at 3750 rpm for 15 minutes at 4° C. 600μL of supernatant was collected and transferred to a new 2 mL clearglass autosampler vial. The samples were then left at −20° C. overnightand then directly centrifuged at 3750 rpm for 15 minutes at 4° C.Extracts were transferred at 4° C. to 200 μL inserts in glassautosampler vials for UPLC analysis.

For UPLC-MS, a quality control sample was generated by pooling a smallaliquot from each sample. This sample was mixed and transferred toindependent vials. The QC sample was injected approximately every 8thinjection. For GC-MS, a QC sample was injected approximately everyseventh injection. This QC sample was prepared by mixing approximatelyequal mass aliquots of samples 1 through 6, to achieve a 2 gram sample.5 mL of 5% ethanol (in water) was added and the sample was shaken for 1hour to extract volatile metabolites. The sample was then centrifuged toremove particulates, and the supernatant transferred to a new vial. 500microliters of this supernatant was transferred to headspace vials forSPME sampling as QC samples.

UPLC-MS Analysis

One microliter of extract was injected onto a Waters Acquity UPLC systemin randomized order. Separation was achieved using a Waters Acquity UPLCCSH Phenyl Hexyl column (1.7 pM, 1.0×100 mm), using a gradient fromsolvent A (water, 0.1% formic acid) to solvent B (Acetonitrile,0.1%formic acid). Injections were made in 100% A, held at 100% A for 1min, ramped to 98% B over 12 minutes, held at 98% B for 3 minutes, andthen returned to starting conditions over 0.05 minutes and allowed tore-equilibrate for 3.95 minutes, with a 200 μL/min constant flow rate.The column and samples were held at 65° C. and 6° C., respectively. Thecolumn eluent was infused into a Waters Xevo G2 Q-TOF-MS with anelectrospray source in positive mode, scanning 50-2000 m/z at 0.2seconds per scan, alternating between MS (6 V collision energy) and MSEmode (15-30 V ramp). Calibration was performed using sodium iodide with1 ppm mass accuracy. The capillary voltage was held at 2200 V, sourcetemp at 150° C., and nitrogen desolvation temp at 350° C. with a flowrate of 800 L/hr.

GC-MS Analysis

Samples (200 mg ground plant material in 10-mL SPME vials) were firstincubated at 40° C. for 10 min, and then the headspace volatiles wereextracted at the same temperature by a SPME fiber (DVB/PDMS/CAR 50/30pm, Stableflex, Sigma-Aldrich) for 25 min, and injected into a DBWAXUIcolumn (30 m×0.25 mm×0.25 pm, Agilent) in a Trace1310 GC (Thermo)coupled to an ISQLT MS (Thermo). SPME fiber desorbed at injection port(250° C.) for 3 min, and then at fiber conditioning port (260° C.) for 3min. GC inlet was operated under split mode (split ratio=5) during fiberdesorption. The oven program started at 40° C. for 3 min, ramped to 170°C. at a rate of 6° C./min, then to 220° C. at a rate of 10° C/min, and afinal hold at 220° C. for 0.3 min. Data were acquired under electronimpact mode, with full scan 45-400 amu and at a rate of 5 scans/second.Transfer line and source temperatures were held at 250° C. QC sampleswere acquired after every 6 samples.

Data Analysis and Statistics

RAMClustR (version 1.0.9) was utilized to cluster features into spectra(Broeckling 2014). XCMS (v.3.6.1) was used for feature detection andretention time alignment. Processing was performed using R (R Core Team2019). Feature data was input as an xcms object with RAMClustR usingdefault parameter selection settings for st, sr and maxt. The featuresimilarity matrix was clustered using fastcluster package heirarchicalclustering method using the average method. The dendrogram was cut usingthe cutreeDynamicTree function from the dynamicTreeCut package. Cuttingparameters were set to minModuleSize=2, hmax=0.5, and deepSplit=FALSE.3032 features were collapsed into 308 spectra. Variance in qualitycontrol samples was described using the RCQC function within RAMClustR.Summary statistics are provided including the relative standarddeviation of QC samples to all samples in PCA space, as well as therelative standard deviation of each feature in QC samples, plotted as ahistogram. Annotations were assigned using the RAMClustR annotatefunction. Smiles structures were retrieved for each inchikey without astructure using the Pubchem API (Djoumbou 2016) called from RAMClustRusing the getSmilesInchi function. Compounds were assigned to chemicalontogenies using the ClassyFire API (Djoumbou 2016).

Principle Component Analysis was performed in R. The SpecAbund datasetwas used as input with scaling set to pareto. The number of principlecomponents was selected using the AuerGervini method from theClassDiscovery R package. The median value of all nPC values from the‘compareAgDimMethods’ function was used to set nPC to 9. Linear modelANOVA was performed for the factor(s) [trt] to provide some guidance onwhich PCs appear responsive to factors of interest. These are not meantto be rigorous statistical tests but to help guide your interpretationof the data. Outlier tests are performed on PC loadings to serve as aguide in interpreting which compounds contribute most to the observedseparation. This is performed using the R pnorm function. Returnedp-values are false discovery rate corrected. These p-values are not usedto conclude that a compound is significantly changing, but rather toindicate that a compound disproportionately contributes to themultivariate sample separation observed for that PC. Analysis ofvariance was performed in R. The SpecAbund dataset was used as input.Fixedfactor linear model ANOVA was performed using the Im function. Themodel used was ‘trt.’ Post-hoc testing was performed for [trt] using the‘Tukey’ method in the Ismeans package.

Study Summaries

The composition tested was able to elicit distinct metabolomic effectsacross the entire collective hemp metabolome both between treatmentgroups and compared to the control group simply by adjusting the timing(i.e., date and/or schedule of application) and frequency (i.e., numberof repetitive applications).

The UPLC-TOF platform detected more than 2,000 compounds. Annotationsusing spectral matching computational interpretation (MSFinder) wereprovided for these metabolites. GCMS using SPME volatile samplingdetected more than 300 compounds. GC-MS annotations are provided usingspectral matching to the NIST spectral database. Principal componentanalysis (PCA) and analysis of variance (ANOVA) statistical approacheswere used to demonstrate treatment effects, with T_1 (Treatment 1), T_2(Treatment 2), T_3 (Treatment 3), and T_6 (Treatment 6) showing thelargest deviations from the control samples.

MeJA treatments applied every 7 days (Treatment 1), every 14 days(Treatment 2), every 28 days (Treatment 3), and only once 72 hours priorto harvest (Treatment 6) substantially altered the non-volatile hempmetabolome (collection of all measured analytes/metabolites) as detectedvia UPLC-MS compared to the Control group metabolome. Treatment 1resulted in the greatest differentiation of the hemp metabolome comparedto the Control group metabolome, followed by Treatment 2, then treatment3, followed by Treatment 4. Metabolome variance increased with thefrequency of treatments and was clearly influenced by the timing of theapplications. Treatment 6 and Treatment 7 resulted in greater deviationfrom the Control group than did Treatments 4 and 5, indicating thatlate-phase applications are more effective at altering metaboliteproduction in planta than single mid-phase or single early-phaseapplications do. Treatment 3 altered metabolite production in plantaless comprehensively than Treatments 1, 2, 6, and 7 but more of itsmetabolome deviation was explained by PC2, indicating that the timingand frequency of elicitor applications alters metabolite production andthe overall metabolome with more complexity than by simply increasing ordecreasing a single set of metabolites.

Of the 2,000+ non-volatile compounds that were detected via UPLC-TOF,597 of them were significantly (p<0.05) altered by one or more treatmentgroups. Five (5) of the 597 (0.83%) putatively belong to the chemicalsuperclass Alkaloids and derivatives, five (5) of the 597 (0.83%)putatively belong to the chemical superclass Benzenoids, 78 of the 597(13%) putatively belong to the chemical superclass Lipid or Lipid like,1 of the 597 (0.16%) putatively belong to the chemical superclassOrganic acids and derivatives, 1 of 597 (0.16%) putatively belong to thechemical superclass Organic nitrogen compounds, 9 of 597 (1.5%)putatively belong to the chemical superclass Organic oxygen compounds,10 of 597 (1.6%) putatively belong to the chemical superclassOrganoheterocyclic compounds, 14 of 597 (2.3%) putatively belong to thechemical superclass Phenylpropanoids and polyketides, and 466 of the 597were not annotated (78%).

Seven of the 78 were further described assphingolipids (one of 7 as a ganglio series, one of 7 as aglycosphingolipid, three of 7 as glucosyl-N-acylsphingosines, one of 7as sulfatide, and one of 7 as phosphosphingolipid). Three of the 78 werefurther described as steroids and derivatives (one of 3 as an estrogenderivative, one of 3 as a gulco/mineralocorticoids, progesteronesderivative, and one of 3 as a sulfated steroid). One of the 78 wasfurther described as purine ribonuclease polyphosphate.

Of the seven (7) putatively labeled Organic acids and derivatives, onewas further described as a dipeptide, one was further described as agamma amino acid, one was further described as a glycosol-amino acid,two were further described as histidine derivatives, one was furtherdescribed as a N-acyl-L-alpha amino acid, and one was further describedas a peptide. The putatively labeled Organonitrogen compound was furtherdescribed as a phosphocholine.

The nine (9) putatively labeled Organooxygen compounds were furtherdescribed as one aminocylitol glycoside, two aminogylcosides, onealkyl-phenylketone, one acyl-aldehyde, one cyclic ketone (importantly,this was putatively labeled as trans-jasmone), one enone, and twopolyethylene glycols.

Furthermore, of the 597 analytes (i.e., compounds) that weresignificantly influenced by treatment (post hoc ANOVA p-value<0.05),Treatment 1 significantly altered the relative abundance of 551 analytescompared to the control group. Treatment 2 significantly altered therelative abundance of 497 analytes compared to the control group.Treatment 3 significantly altered the relative abundance of 41 analytescompared to the control group. Treatment 4 (only one application on thefirst day of flowering) did not significantly altered the relativeabundance of any analytes compared to the control group. Treatment 5significantly altered the relative abundance of 4 analytes compared tothe control group. Treatment 6 significantly altered the relativeabundance of 399 analytes compared to the control group, and Treatment 7significantly altered the relative abundance of 216 analytes compared tothe control group.

The effect of each treatment compared to the control and to each otherin terms of impact on the relative abundance of analytes is notable, asit indicates that the efficacy of MeJA, and likely other jasmonate-typeelicitor applications, is largely dependent on application frequency andtiming. Frequent applications (every 7-14 days, T1 and T2) elicited thegreatest deviation in metabolite content. Pre-harvest applications (T6and T7) elicited the second greatest deviation in plant metabolicresponse, although the speed at which the plant can respond must beconsidered (e.g., 72 hours vs 24 hours). Single, mid-flower phasetreatment applications (T4, T5) were the least effective at manipulatingthe metabolite profile in planta. This is likely due to the fact thatthe effects of the elicitor had worn off by the time the plants wereharvested.

Other notable putatively annotated analytes of interest thatsignificantly differed OW p-value<0.05) from the control groupmeasurements include numerous jasmonate derivatives including7-Epi-12-hydroxyjasmonic acid glucoside_1, N-Jasmonoylisoleucine_1,7-Epi-12-hydroxyjasmonic acid glucoside_2, Jasmine ketolactone_1,Jasmonic acid_1, Jasmine ketolactone_2, Jasmonic acid_2, Jasmonicacid_3, N-[(+)-12-hydroxy-7-isojasmonyl] Lisoleucinate, Jasmonic acid_4,Jasmolone glucoside, (−)-12-hydroxy-9,10-dihydrojasmonic acid,trans-Jasmone, Jasmonic acid_5, and Jasmonic acid_6. This indicates thatexogenous application of a jasmonate elicitor like MeJA is able toincrease endogenous levels of numerous jasmonate derivaties.

Other significantly (p-value<0.05) altered putatively annotatedmetabolites of interest in treatment groups relative to the controlgroup include precursor compounds to numerous metabolites of interest(Geranylfarnesyl diphosphate_1, Geranylfarnesyl diphosphate_2, and6-Geranylgeranyl S′-methyl 6,8′-diapocarotene-6,8′-dioate), carboxylicacid derivatives and jasmonic acid isomers (Tuberonic acid_2, Tuberonicacid_3, Tuberonic acid_4),(16alpha,20R,24S)-2,16,20,25-tetrahydroxy-24-methoxycucurbita-1,5-diene-3,11,22-trione2-0-beta-D-glucopyranoside, Cucurbitacin C, Cucurbitacin D,(1S,2S)-3-Oxo-2[(2Z)-pentenyl]cyclopentane-1-butyric acid, Tetraethyleneglycol_2, Tetraethylene glycol_1, Citronellyl acetate_1, Corticatic acidA_1, Soyasaponin II (triterpenoid saponin), Butyric acid (similar chainfound off C5 on cyclopentanone rings in jasmonates), Adenosine5′-pentaphosphate, Tephrowatsin A_2 (a hydroxyflavin),N-trans-Feruloyloctopamine 1 (carboxylic acid, cinnamate, coumaricacid), Terretonin (tetricyclic monoterpenoid), Caffeine_1, AlismorientolA (guaiane sesquiterpenoid), 2,3-didehydropimeloyl-CoA (derivative ofcoenzyme A), Lucidenic acid E2 (triterpenoid), Amastatin (tetrapeptide),Yiamoloside B (triterpenoid saponin), Glucoliquiritin apioside(flavonoid), Myristoleic acid_3 (tetradecenoic acid), (+)-DictyopanineA; Dictyopanin A; Dictyopanine A (polycyclic aromatic hydrocarbonindene), Candicanoside A; (−)-Candicanoside A (saponin), NotoginsenosideT1_1 (triterpenoid found in ginseng), Sarsasapogenin_1(terpenoid-steroid-spirostan), ardimerin digallate (dimeric lactone),Rhynchophylline (a indolizine, alkaloid precursor), Schweinfurthin F;(+)-Schweinfurthin F (member of resorcinols and a stilbenoid),25-Cinnamoyl-vulgaroside (found in fruits), Epitaondiol diacetate,Chikusetsusaponin 1a (steroid saponin found in ginseng), Ningpeisinoside(glycoside), Petroselinic acid (cis isomer of octadec-6-enoic acid),Sinapoyl-CoA (coenzyme A derivative), Diginatin_1 (Diginatin is acardenolide glycoside), Pilocarpine (alkaloid w/cholinergic activity andis an antiglaucoma drug), Caseargrewiin C; (+)-Caseargrewiin C(diterpenoid), Ophiopogonin C′_1 (saponin glycoside), Citroside A_1(terpene glycoside), LSM-S512 (proline derivative), beta-Hederin(triterpenoid), Presqualene diphosphate_1 (intermediate in biosynthesisof terpenoid; a substrate for Farnesvl-diphosphate farnesvltransferase).

Some influence on carotenoid biosynthesis wasobserved.

Example 2: Application of MeJA, MDJ, and CJ to High-CBD Hemp VarietiesAlters Cannabinoid and Terpene Production

In Applicant's previous experiments (Example 1 above, data figures inprovisional application 63/057,549, incorporated herein by reference,and US Patent Application Publication No. 2019/0059371), applications ofMeJA demonstrated significant bioactivity and biostimulation regardingthe production of secondary metabolites like cannabinoids. However, MDJis not known to have any significant bioactivity in planta and is not anendogenously produced phytohormone in Cannabis, so it was unknownwhether MDJ would afford the same functionality as MeJA. Similarly, CJhas likewise been relatively under-investigated as a plant elicitordespite being a decarboxylation product of Jasmonic Acid. Here, theeffect of MDJ and CJ were analyzed (in addition to MeJA) in order todetermine any difference in the effect of these treatments onfield-grown high-CBD hemp varieties.

A hemp field experiment was conducted during the flowering phase ofplant development in a private research field located in North Carolina.Sixty (60) plants from two distinct plant variety populations, StormyDaniels and BaOX were selected for the trial. Each group of 60 plantswas randomly divided into three groups of 20 plants and labeledaccordingly to indicate the treatment group (T1, T2, T3). All plantswere cultivated identically and subjected to approximately the sameenvironmental conditions. Control, untreated plants were taken from thesame field. Plants were treated according to treatment group, and eachtreatment group was subjected to four (4) applications of its respectivetreatment, with the first treatments applied on what was considered tobe the first day of the flowering phase and repeated then again everysuccessive 14 days up until just prior to harvest. Treatments were asfollows: Control group=Control, Treatment 1=MDJ, Treatment 2=MeJA,Treatment 3=CJ.

All treatments were prepared in a stock (concentrated, non-aqueous) formby Impello Biosciences in their lab in Loveland, Colo. and labeledrespectively prior to the start of the experiment. All treatments wereprepared at a high stock concentration that allowed dilution by theapplicator with 2 liters of water to a final 7.5 mM concentration ofactive ingredient (i.e., MeJA, MDJ, or CJ) for each treatment; 15-mLcentrifuge tubes were used as preparation and storage vessels for eachof the treatments. Preparation of the stock solutions ensured that theapplicator could store the solutions prior to use at 4° C. to minimizedegradation and allow for dilution immediately prior to use. In thestock containers, 2 mL of TWEEN®-20 was added to each respectiveelicitor compound as an emulsifier in order to reach a finaloil-in-water emulsion once diluted with a concentration of 7.5 mM activeingredient and 0.1% surfactant (i.e., TWEEN®-20) v/v.

Plants were grown to maturity and 5 plants from each treatment andcontrol group were sampled on Sep. 23, 2019. Care was taken to ensuresamples were similar in appearance and spatial location between plantsto minimize unintended variance in sample quality. The apical cola foreach plant was harvested, and specifically, the top 3″ of the main cola.Yield data was not collected in this study, but no obvious differencesin plant size or appearance were noted. Samples were submitted forchemical analysis (Avazyme, Inc, NC).

Statistical analysis of the quantitative metabolite data was performedin R statistical software and shown in FIG. 1A-1E. All models werelinear models fit with Group (treatment) as the independent variable andthe response variable was the corresponding compound. Data was filteredand comparison between treatments were conducted using the emmeanspackage and Tukey HSD for post-hoc corrections. Statistical significancewas defined by a level of significance of p<0.05 in the Tukey test.Total cannabinoids included CBN, Δ9-THC, CBDV, CBG, CBD, CBC, CBDA,CBGA, THCA, and THCV. Total THC and total CBD were calculated byaccounting for the additional weight of the carboxyl group in the acidicforms and adding those to the neutral/non-acidic forms.

Treatment group 3 (cis-jasmone) showed significantly increased levels ofthe following cannabinoids relative to the control group at a confidenceof p<0.05: Total THC (+27.09%) (FIG. 1A), Total CBD (+23.64) (FIG. 1B),Total Cannabinoids (+22.92%) (FIG. 1C), THCA (+27.23%) (FIG. 1D), andCBDA (+23.61% increase) (FIG. 1E).

MDJ treatments (T1) increased the following cannabinoids relative to thecontrol group: Total THC (+19.61%) (FIG. 1A), Total CBD (+16.62%) (FIG.1B), Total Cannabinoids (+16.38%) (FIG. 1C), THCA (+19.69%) (FIG. 1D),and CBDA (+16.53%) (FIG. 1E).

Likewise, MeJA (T2) treatments consistently increased the followingcannabinoids relative to the control group: Total THC (+6.06%) (FIG.1A), Total CBD (+5.75%) (FIG. 1B), Total Cannabinoids (+5.64%) (FIG.1C), THCA (+5.36%) (FIG. 1D), and CBDA (+5.36%) (FIG. 1E).

In summary, all treatment groups returned higher cannabinoid values foreach measured cannabinoid analyte compared to the control group.Notably, each treatment demonstrated consistent increases to cannabinoidproduction that shows practical significance in terms of real-lifeapplication scenarios. These preliminary findings encourage furtherresearch with these same jasmonate-type compounds with larger trialpopulations and indicate that CJ is a viable jasmonate compound for useto alter plant metabolite by applications in planta on some plantvarieties.

Example 3: Low-Volume Foliar Applications of MeJA or MDJ on High-CBDHemp Varieties in the Morning or Evening Alters Cannabinoid and TerpeneProduction

In previous foliar application experiments, plants were sprayed untilthe leaves were dripping. In order to assess the plant physiologicalresponse to low-volume foliar applications of two jasmonate elicitors,methyl jasmonate (MeJA) and methyl dihydro-jasmonate (MDJ), an outdoorexperiment on field grown, high-CBD hemp was designed and performedduring the summer of 2019 using an unmanned aerial drone as theapplication device. A single high-CBD hemp variety, “Cherry” (CBDRx,Longmont, Colo.) was used in an organic field plot in Pueblo, Colo.,which was subdivided into four spatially separated quadrants ofapproximately 0.5 acres each as determined by drone and GPS mapping.Each 0.5-acre quadrant was assigned a treatment group, and the middlearea of the entire plot, approximately 1 acre in area, was used as a“control” section of the field. Plants in the Control group receivedsprays of water and TWEEN®-20 only, identical to the treatment groupsexcept for the exclusion of any jasmonate (i.e., [0 mM] MeJA and MDJ)active ingredients. MeJA and MDJ were applied at approximately 2 gallonsper acre. In comparison, previous foliar applications wherein the plantwas sprayed until the leaves dripped would equate to between 50-100gallons per acre.

Treatments were separated into such “morning” and “evening” applicationsin an attempt to determine if the time of day influenced the plantresponse to the treatments. The four treatment groups were as follows:T1M=[7.5 mM] MDJ foliar applications in the morning; T1E=[7.5 mM] MDJfoliar applications in the evening; T2M=[7.5 mM] MeJA foliarapplications in the morning; T2E=[7.5 mM] MeJA foliar applications inthe evening. All treatment groups were prepared the day of theapplication, and all applications were made successively with the samedrone device. To reduce potential cross-contamination of the dronesprayer equipment, an acetic acid solution (5%) was run through theapplicator equipment between each treatment application and controlspray application, followed by plain water as a final rinse.

Plants were planted and allowed to grow in the normal fashion until theonset of flowering, which occurred around Jul. 25, 2019. At that point,foliar applications of the treatment were made approximately every 14days with adjustments to the schedule as needed to avoid applyingtreatments on days with high winds, rain, or other suboptimal conditionsfor drone flight or treatment applications. Approximately every 14 daysduring the flowering cycle, flower samples from three randomly selectedplants in each experimental group were taken, dried, and stored foranalytical testing; however, the focus of this study was to determinethe effect of the treatment groups versus the control group at harvest.Final flower samples were taken from 10 randomly selected plants in eachexperimental group on September 12, 2019, labeled accordingly, dried,and sent to a third part commercial Cannabis testing lab (Pro Verde,Milford, MA) for chemical analysis of the cannabinoids and terpenecontent individually using liquid chromatography (LC) and headspace gaschromatography (HS-GC), respectively. All samples were harvested on theday of a scheduled treatment prior to treatment.

Pre-harvest samples did not indicate any difference between morning orevening application, thus only the morning samples from the finalharvest were analysed. Statistical analysis of the quantitative terpenedata from plant samples taken at harvest was performed using Rstatistical software and corrected post-hoc using Tukey HSD method. Forcannabinoid data from the same plant samples, ANOVA analysis wasperformed in Microsoft Excel with Tukey HSD post-hoc corrections.

A notable and statistically significant increase in the ratio of CBD:THCwas observed in both T1M (MDJ) (+2.53%, p=0.002) and in T2M (MeJA)(+1.76%, p=0.0346) compared to the Control group. This metabolicalteration is particularly important to hemp growers and indicates avaluable shift in the plant's metabolome following treatment; theCBD:THC ratio is a good indicator of “usable” hemp metabolites versus“unusable” hemp metabolites from a producer's perspective.

Additionally, a number of terpene analytes were notably increased inboth treatment groups compared to the control. Significant (p≤0.05)differences were observed in Treatment 1 (MDJ) compared to the Controlgroup. Similar differences were observed between the same analytes inthe Treatment 2 (MJ) group compared to the Control group.

The terpene analyte alpha bisabolol was significantly increased in theMDJ treatment compared to the Control group (+17.2%, p=0.013, whereasalpha bisabolol was actually decreased in the MeJA treatment group.

Additionally, the following terpenes were increased in Treatment 1compared to the Control group: trans-nerolidol (+66.66%),beta-caryophyllene (+3.3%), guaiol (+5.66%), and alpha-humulene(+3.15%). Notably, of all the measured terpene analytes in thisexperiment, which can be separated into monoterpenes and sesquiterpenes,all sesquiterpenes were increased in Treatment groups compared to theControl group, and all monoterpenes were decreased in Treatment groupscompared to the Control group, indicating an unexpected terpeneclass-wide response. Monoterpene analytes that were decreased inTreatment groups 1 and/or 2 include: beta-myrcene, beta-pinene,eucalyptol, alpha-pinene, and d-limonene.

Experiment Summary: Surprisingly, low-volume exogenous foliarapplications of the elicitor MeJA were still capable of eliciting ametabolomic shift in a high-CBD hemp variety in a field setting. Theplant response was most notable in the production of terpenes, where anobvious trend was observed in terpenes of two distinct classes:monoterpenes and sesquiterpenes. This suggests that MeJA and otherjasmonate elicitors can be effective at shifting the plant metabolomefavourably and relatively consistently and predictably, which can beuncommon and difficult with plant growth regulating compounds in a fieldenvironment.

Example 4: Application of MS+MDJ in Combination on a High-CBD VarietyAlters Cannabinoid and Terpene Production Provides Plant Growth Benefits

Methyl salicylate (MS) is an antagonistic compound to the jasmonates. Toinvestigate the effect of MS alone and in conjunction with MDJ, MS (CASNo.: 119-36-8), MDJ, and the combination (MS+MDJ) were applied by foliarspray to CBDRx Cherry hemp clones once per week during both vegetativeand flowering phases. Plants were transplanted into 1-gallon pots withRed's soil and put into vegetative light cycle (18L/6D). There were fourplants per treatment group, including the control group which did notreceive any foliar applications. Plants were grown under a total of 12Boost (Thrive Agritech, N.Y.) 130-watt LED lights set to 18L: 6Dphotoperiod during the vegetative phase (2 weeks) and this was followedby a 12L: 12D photoperiod during the flowering phase (7 weeks), usingthe same lighting fixtures. Throughout the nine weeks, all plants werewatered when needed with Jack's nutrients.

MS or MDJ treatments were applied at the following concentrations: [1mM], [4.25 mM], [7.5 mM] and [10 mM]. Each concentration was preparedfrom a one molar stock solution diluted with RO water and TWEEN®-20 (1Mstock) was added. Each plant was sprayed till dripping, which wasapproximately 50-75 ml. To apply the combination of the twobiochemicals, MS and MDJ were sprayed separately but simultaneously, toensure each compound was applied evenly onto the plant. Each compoundwas applied using a SPRAYMASTER Chemical Sprayer (King of Prussia, PA).

Plants were harvested two months after transplant. After harvesting,plants were air dried at room temperature for two weeks. Once plantswere sufficiently dry, above ground dry weights were recorded and driedflower samples were collected and sent to a third-party lab for terpeneand cannabinoid analysis. Two plants (#3 and #4) in treatment group MDJ[7.5] mM, two plants (#3 and #4) in MS [4.25] mM, one plant (#4) in MS[7.5], and one plant (#4) in MDJ [10] died before the end of theexperiment.

Biomass Results

All concentrations of MDJ had beneficial plant growth effects on clonalhemp plants in the vegetative stage compared to all testedconcentrations of MS (FIG. 2A-2D, MS+MDJ combination not shown).Aboveground fresh weight and dried weight was significantly reduced inthe MS group compared to the control plants, at both 1 mM and 10 mM(FIG. 2E-2F). Pairwise comparisons (Tukey's honestly significantdifference test of anova model) is shown below in Table 3a and 3b. Allother treatments vs control were not significant.

Example 5: Application of MDJ or CJ to a High-THC Marijuana VarietyAlters Cannabinoid Production

Applicant's previous experiments investigated the effects ofjasmonate-type elicitors MeJA, MDJ, and CJ on hemp (high fiber) andhigh-CBD, (low-THC) varieties of Cannabis. Additionally, in some casesMDJ and CJ had been shown to be more effective than MeJA. Here, theeffects of MDJ and CJ application on a high-THC variety in a controlledenvironment was investigated. High-THC, low-CBD marijuana variety “LemonCreamsicle” (LC), was grown in a greenhouse setting. LC was used as aplant model due to its historically consistent metabolite profile in thegreenhouse environment, making it a stable, known, and reliable variety.

A four-block plant trial was implemented with a population of N=12plants and treatment group sizes of n=4. The treatment and controlgroups were defined as follows: Control=water+0.1% TWEEN®-20 aqueousfoliar spray, Treatment 1=[7.5 mM] CJ+0.1% TWEEN®-20 aqueous foliarspray, Treatment 2=[7.5 mM] MDJ+0.1% TWEEN®-20 aqueous foliar spray. Astandardized concentration of [7.5 mM] for both CJ and MDJ applicationswas chosen due to its performance in Applicant's past research. Alltreatment solutions were prepared the day of the application in equalvolumes from pre-measured quantities of the stock materials to ensureconsistency, i.e., appropriate volumes of CJ or MDJ were combined withappropriate volumes of TWEEN®-20 for each experimental treatment, storedin a sealed centrifuge tube, and diluted in the appropriate amount ofwater immediately prior to application. Separate sprayers were used foreach treatment and control sprays to avoid cross-contamination.

All plants in the trial were produced as asexual clone stock taken fromthe same mother plant at the same time to ensure homogeneity. All plantswere rooted and grown in accordance with the production practicestypical to this greenhouse operator prior to plant selection for theexperiment. Due to the layout of the cultivation system, which featuresimmovable hydroponic “pots” that house the plant throughout the entireflowering (i.e., reproductive) phase, all plants included in theexperiment were selected from a set section of the greenhouse afterfinal transplant into the hydroponic system and grouped in a completerandomized block design accordingly.

After defining the plants to include in the experiment, which wereorganized in two (2) rows of six (6) plants side-by-side in thehydroponic system, the experimental blocks were defined as groups ofthree plants, and a research randomizer tool (randomizer.org) was usedto generate a randomized arrangement of plants in each group. Using ablocked design in this setting helped account for the immovable natureof the plants and the slight, if any, environmental differences (likenatural sunlight, shading from other plants, and corner/edge effect)that existed in the small experimental area. Blocking the experimentalarrangement also allowed for improved statistical analysis andresolution considering the small sample size and close proximity of theexperimental plants.

After labeling each plant in the experiment with the appropriate grouplabel (Control, T1 [CJ], or T2 [MDJ]), the plants were allowed to grownormally between treatment applications, which were performed every 14days for a total of four (4) treatments throughout the flowering cycle,which lasted approximately eight (8) weeks. The first treatment occurredseven (7) days after the onset of the flowering cycle, which wasdictated by day-length control. Care was taken with each treatmentapplication to minimize overspray onto non-target neighboring plants,and physical barriers were temporarily installed between plants duringtreatment sprays to aid in this effort. These barriers were removedfollowing treatment sprays when the foliage was no longer visibly wetfrom the treatment and/or control foliar sprays. Each plant in theexperiment was sprayed with the appropriate treatment or controlsolution until dripping to ensure good coverage, and applications weremade during the daylight hours with supplemental lighting turned off andfull sun exposure.

Upon conclusion of the flowering cycle, when the plants were deemedready for harvest, each plant was harvested in a typical fashion andhung to dry in accordance with the standard practices of the greenhouseoperator. Each plant was tracked with an ID tag. No obvious visualdifferences in plant size, structure, or appearance were observed. Oncethe plant material was deemed sufficiently dry, representative flowersamples of approximately 5 grams from each plant were taken andsubmitted individually for analysis by a commercial Cannabis testing lab(RM3 Labs Colorado LLC). Analytical results were returned in aspreadsheet format with metabolite results listed for each plant in theexperiment.

Statistical analysis of the quantitative metabolite data was performedin R statistical software. All models were linear models fit with Group(treatment) as the independent variable and the response variable wasthe corresponding compound. Data was filtered and comparison betweentreatments were conducted using the emmeans package and Tukey HSD forpost-hoc corrections. Statistical significance was defined by a level ofsignificance of p<0.05 in the Tukey test.

Both MDJ and CJ treatments resulted in higher average THCA, TotalCannabinoids, CBGA, and Total THC (THCA+THC) compared to the Controlgroup averages. Average relative percent increases for MDJ treatmentgroups compared to the Control group per cannabinoid are as follows:THCA +6.88%, Total Cannabinoids +6.06%, CBGA +15.91%, and Total THC+5.92%.

Average relative percent increases for CJ treatment groups compared tothe Control group per cannabinoid are as follows: THCA +1.13%, TotalCannabinoids +1.17%, CBGA +11.22%, Total THC +1.03%.

Statistically significant differences were found in comparisons of theControl group values to the Treatment 2 (MDJ) group values for thefollowing metabolites: total cannabinoids (p=0.0155, +6.06% relativeincrease) (FIGS. 3A & 3B); notably, the observed differences in totalcannabinoids between T1 and T2 groups was also significant (p=0.0385)(FIG. 3A), and THCA (p=0.0260, +6.88% relative increase) (FIGS. 3C &3D).

Collectively, these results demonstrate that even in high-cannabinoidyielding commercial Cannabis varieties, the biochemical elicitors MDJand CJ can further increase the production of valuable metabolitesbeyond what the plant would otherwise produce without treatment.

Example 6: Foliar Spray of MDJ Successfully Alters Cannabinoids andTerpenes

Previous experiments showed that 7.5 mM MDJ could not only elicit ametabolite response, it also elicited a greater response than 7.5 mMMeJA (see for example, Examples 3 and 4 above). To investigate theeffect of different concentrations of MDJ, four different concentrationsof MDJ was applied to hemp plants (n=5 per treatment, Cv.: Zephyr,CBDRx) weekly via foliar spray at the following concentrations: 1 mM,4.25 mM, 7.5 mM, 10 mM. Treatment concentrations were prepared asdescribed above and one drop of TWEEN®-20 (VWR, CAS No.: 9005-64-5) wasadded to treatments to serve as a surfactant. Treatments were appliedweekly during both the vegetative (2 treatments) and flowering (6treatments) developmental stages using a SPRAYMASTER Chemical Sprayer(King of Prussia, PA) (8 treatments total). Plants were grown under atotal of 12 Boost (Thrive Agritech, NY) 130-watt LED lights set to 18L:6D photoperiod during the vegetative phase (2 weeks) followed by a 12L:12D photoperiod during the flowering phase (6 weeks), using the samelighting. Untreated controls served as a comparison to see alterationsin metabolite synthesis.

As shown in FIGS. 4A-4J, several cannabinoids were altered by the foliarspray application of MDJ. All tested concentrations of MDJ significantlyincreased total CBD (FIG. 4B), total CBG (FIG. 4C), total cannabinoids(FIG. 4D), CBDA (FIG. 4E), CBGA (FIG. 4F), and THCA (FIG. 4H). While CBLwas not detected at all in the control samples, application of MDJyielded detectable levels. As shown in FIGS. 5A-5H, several terpeneswere altered by the foliar spray application of MDJ.

Example 7: MDJ is More Effective than MeJA at Altering the Production ofTerpenes

To directly compare the efficacy of MeJA and MDJ, MeJA and MDJ wereapplied as a foliar spray once per week at either 4.25 mM or 7.5 mMconcentrations to two high-CBD Cannabis varieties. Clones from CBDRxCherry variety and Sunrise Genetics' F2 variety were transplanted into1-gallon pots with Red's soil and put into vegetative light cycle(18L/6D) on Apr. 12, 2021. All plants had two weeks in vegetative lightcycle and were moved to flowering light cycle (12L/12D) on Apr. 26, 2021for six weeks. Foliar applications started in week three of growth, [atflower initiation?]. Plants were then moved to a flowering light cycle.Each treatment group comprises three plants, including the control.Throughout the growing period, all plants were watered with JACK'SNUTRIENTS®. Plants were harvested on Jun. 7, 2021.

Treatments: Each concentration was prepared from a one molar stocksolution with TWEEN®-20. Sprays were prepared weekly and diluted with ROwater. Each plant was sprayed till dripping, each receivingapproximately 75-100 ml. No significant changes in plant biomass wasobserved in any treatment group.

As shown in FIG. 6A, application of 4.25 mM or 7.5 mM MDJ to the Cherryvariety significantly lowered β-myrcene content. These concentrations ofMDJ also significantly lowered α-pinene (FIG. 6B), camphene (FIG. 6C),β-pinene (FIG. 6D), and total terpene content (FIG. 6E), whereas neitherconcentration of MeJA significantly altered these terpenes.

A similar result was seen variety F2. As shown in FIG. 6F, applicationof 4.25 mM or 7.5 mM MDJ to the F2 variety significantly loweredβ-myrcene content. The same was true for α-pinene (FIG. 6G), camphene(FIG. 6H), β-pinene (FIG. 6I), and total terpene content (FIG. 6J). Herehowever, significant reduction was also observed with MeJA, but onlywith the higher concentration of 7.5 mM. Significant increases wereobserved in α-bisabolol, guaiol, and eucalyptol with applications of4.25 mM or 7.5 mM MDJ, or application of 7.5 mM MeJA. D-Limonene andcis-B-ocimene were significantly decreased with all applications of MDJor MeJA, and Linalool was significantly increased with all applicationsof MDJ or MeJA.

Example 8: Root Drench of MeJA or MDJ Above 10 mM is Phytotoxic toCannabis

Previous data showed that root drench of MDJ using bean and tomatomodels were effective up to 10 mM. To investigate if higherconcentrations of jasmonate elicitors would be tolerated in Cannabis byroot drench, four different concentrations, [7.5 mM], [10 mM], [15 mM]and [20 mM] were applied to hemp clones (n=4 per treatment group, cv.:Cherry, CBDRx) in the vegetative stage. Treatment concentrations wereprepared from methyl dihydrojasmonate (MDJ, TCI, CAS No.: 24851-98-7)and methyl Jasmonate (MeJA, TCI, CAS No.: 1101843-02-0) with 1%TWEEN®-20 added (VWR, CAS No.: 9005-65-5).

The roots of each clone in each treatment group were treated with 250 mLof each compound once per week. Plants were grown under a total of 12Boost (Thrive Agritech, NY) 130-watt LED lights set to 18L: 6Dphotoperiod during the vegetative phase (2 weeks) or until phytotoxicityobserved.

As shown in FIGS. 7A and 7B, concentrations above 10 mM of both MDJ andMeJA were phytotoxic to plants in the vegetative stage within 72 hours(FIGS. 7A and 7B). For MeJA, three out of four plants in the 15 mMtreatment were deceased in 72 hours, and three out of four plants in the20 mM treatment were deceased in 72 hours (FIG. 7A). For MDJ, three outof four plants in the 10 mM treatment were deceased in 72 hours, and allfour plants in each of the 15 mM and 20 mM treatment groups weredeceased in 72 hours (FIG. 7B).

Example 9: MDJ and CJ Inhibit Fungal Growth

As jasmonates are known to play a role in plant defense, an experimentwas designed to test their potential role in prohibiting plantpathogens, such as fungi.

MDJ (TCI, CAS No.: 24851-98-7) and CJ were infused into potato dextroseagar (PDA, VWR Cat No.: 90003-494) petri dishes (100×15 mm VWR, Cat No:25384-094) at concentrations ranging from 1 mM, 4.25 mM, and 10 mM. Eachtreatment was prepared using a technical grade stock solution of purechemical (CJ or MDJ) diluted with TWEEN®-20 (VWR, CAS No.: 9005-65-5).Culturable oyster mushroom and seedling mold served to create fungalmycelial plugs using a sterile 1 mL pipette tip (Eppendorf, Cat No.:022491458) held upside down. The tips were used to make circle excisions(i.e., fungal plugs) from a mycelial mat grown on PDA with nobiochemical infusions. Fungal pugs were then transferred to PDA infusedwith varying concentrations of CJ or MDJ, and control plates (no CJ orMDJ infusion) to monitor fungal growth at room temperature over time.

Results: As shown in FIGS. 8A-8D, all concentrations of MDJ and CJshowed inhibition of Oyster mushroom fungal growth when compared tocontrol. Few differences in efficacy were observed between all testedMDJ and CJ concentrations. Shown in FIGS. 8A-8B are plates of Oystermushroom at 72 hours (FIG. 8A) and 10 days (FIG. 8B) post inoculation.Control plates are shown on the top row, followed by concentrations ofMDJ or CJ at 1 mM, 4.25 mM, and 10 mM (left to right, in duplicate).

As shown in FIGS. 8C-8D, all concentrations of MDJ and CJ showedinhibition of seedling mold growth when compared to control. Fewdifferences in efficacy were observed between all tested MDJ and CJconcentrations. Shown in FIGS. 8C-8D are plates of seedling mold at 72hours (FIG. 8C) and 10 days (FIG. 8D) post inoculation. Control platesare shown on the top row, followed by concentrations of MDJ or CJ at 1mM, 4.25 mM, and 10 mM (left to right, in duplicate).

Example 10: MDJ is More Effective than MeJA at Inhibiting Fungal Growthat Lower Concentrations

To compare the efficacy of MDJ and MeJA at inhibiting the same seedlingmold as used in the experiment above, a second experiment was conductedusing PDA plates infused with either MDJ or MeJA at differentconcentrations. All plates were generated and inoculated as describedabove and incubated at room temperature under identical conditions.Shown in FIGS. 9A-9C are plates of seedling mold 72 hours post fungalinoculation. Control plates are shown on the top row, followed byconcentrations of MeJA (left) and MDJ (right) in duplicate at 1 mM (FIG.9A), 4.25 mM (FIG. 9B), and 10 mM (FIG. 9C). While both MDJ and MeJAinhibited seedling mold growth, MDJ was more effective at the 1 mMconcentration (FIG. 9A). Subsequent sequence analysis identified the“seedling mold” as Trichoderma ghanense.

A grey mold was also tested (FIGS. 10A-10D). All plates were generatedand inoculated as described above and incubated at room temperatureunder identical conditions. Shown in FIGS. 9A-9C are plates of grey mold72 hours post fungal inoculation. Control plates are shown on the toprow, followed by concentrations of MeJA (left) and MDJ (right) induplicate at 1 mM (FIG. 10A), 4.25 mM (FIG. 10B), and 10 mM (FIG. 10C).While both MDJ and MeJA inhibited grey mold growth, MDJ appeared to bemore effective at inhibiting grey mold at the 1 mM concentration (FIG.10A). However, MeJA appeared to more effective than MDJ at 4.25 mM and10 mM concentrations (FIGS. 10B and 10D). While it was initiallyhypothesized that the grey mod was a species of Botrytis, subsequentsequence analysis identified the mold as Rhizopus stolonifera.

Example 11: Jasmonates are Effective at Slowing or Stopping the Growthof a Variety of Plant Pathogens

Based on the above results in Cannabis spp., additional fungi fromvarious crops was sampled and tested. Plates comprising variousconcentrations of MDJ or MJ were prepared as described above. As shownin FIGS. 11A-11E, both MDJ and MJ were effective at preventing thegrowth of mold isolated from avocado, sweet potato (FIG. 12 ), orange(FIG. 13A-13B), tomato (FIG. 14A-14B), strawberry (FIG. 15A-15B), andpineapple (FIG. 16 ). Each mold was subsequently isolated and identifiedby sequence analysis, shown in Table 6 below.

For fruit MDJ dips, all fruits were purchased from a local market ascertified organic on Apr. 13, 2021. Before any treatments, all fruitswere submerged in boiling water to melt off any non-natural waxy coatingthen dried with a washcloth. Once fruits were clean and dry, they weresubmerged in varying concentrations of methyl dihydrojasmonatesolutions. Each solution was prepared from a 1M MDJ Tween 20 stocksolution diluted with RO water. 500 ml of each solution was prepared andreused for the different fruits. Each fruit was submerged for 20 secondsand then left to dry on a paper towel. After the fruits were dry thepaper towels were removed and fruits left on the lab bench at roomtemperature grouped by treatment but not touching and monitored forvisual differences for 2 weeks. The pineapple was the only fruit thatwas not fully submerged but instead sprayed till drip with the varyingconcentration of MDJ/Tween 20 solution. Then left to dry and monitoredthe same as the other fruits.

Treatments and Sample Sizes:

-   Control, water—4 lemons, 2 oranges, 1 pineapple, 1 mango, 4    strawberries, 2 grapes (˜10 grapes/bundle), 2 oranges, 4 avocados-   [5] mM MDJ—4 lemons, 3 oranges, 1 pineapple, 1 mango, 4    strawberries, 2 grapes, 2 oranges, 4 avocados-   [10] mM MDJ—4 lemons, 3 oranges, 0 pineapple, 1 mango, 4    strawberries, 2 grapes, 2 oranges, 4 avocados-   [20] mM MDJ—5 lemons, 3 oranges, 1 pineapple, 1 mango, 4    strawberries, 2 grapes, 2 oranges, 4 avocados

Qualitative observations like color changes, firmness, mold appearancewere monitored and at the end of the two weeks all fruits were cut inhalf to record and further observations. Penetrometer readings wererecorded in the last week of observations.

The lemons showed no distinct visual differences externally orinternally, however, slight browning was observed in all groups and allgroups had even firmness. The blood oranges had no mold in any of thetreatment groups throughout the observation period. They all showed evensigns of browning on the peel, and unlike the lemons, got softer overtime. No quantitative firmness data was recorded.

The pineapples showed some mold, later identified as Penicilliumsolitum, at the base of the pineapple in all three treatment groups,however there was only one pineapple per treatment group, and the [10]mM was not included. The control had the greenest crown, followed by the[5] mM, then [20] mM which had the most dried out crown.

The mangoes also only had one fruit per treatment group, but all fourtreatments applied. The mangoes showed no differences on the outside,but when cut open there was a clear trend of internal browning. The mostobserved in the control group, and slightly less in the [5] mM group,less still in the [10] mM, and no clear browning in the [20] mM group(FIG. 17 ).

The strawberries had mold in all groups after one week, however atreatment of 1 M MDJ prohibited mold for two weeks (FIG. 15B). Thegrapes did not exhibit any mold, or observable difference betweengroups. The oranges became much firmer over time, and there was noappearance of mold.

The avocados showed more external browning in the control group, [10] mMand [20] mM groups (FIG. 11E). When the fruits were cut open, the [5] mMgroup had the least signs of browning, whereas one avocado showedsignificant signs of browning in each of the other treatment groups.

Example 12: MDJ is Effective at Preventing Biomass Loss Due to FusariumVentricosum Infection

To investigate the efficacy of MDJ at inhibiting Fusarium ventricosum,plants of the Cannabis variety ‘Jack Herer’ were infected and treatedwith either 1 mM or 10 mM MDJ. Briefly, after two weeks in vegetativelight cycle, ‘Jack Herer’ plants were moved to flowering cycle andsprayed with 1 mM or 10 mM methyl dihydrojasmonate on Apr. 12, 2021.After 72 hours (Apr. 15, 2021) all plants were infected with Fusariumventricosum cultured on potato dextrose agar. Plants were infected usinga fungal pick to inoculate the fungal culture at the stem of the plant.No visual signs of infection were observed after two weeks, so allplants were reinfected using a PDA and liquid culture of F. ventricosumon Apr. 28, 2021 and again on May 14, 2021. Plants were harvested andhung to dry on Jun. 11, 2021 and dry weights recorded on Jun. 16, 2021.After harvest, stem tissue was taken from each treatment group andplated onto potato dextrose agar. Fusarium ventricosum was reisolatedfrom each group.

Compared to the control group, both treatments showed a prevention inbiomass reduction due to Fusarium infection. Both treatment groups (1 mMand 10 mM) had more yellow, wilting leaves compared to the control, buthad larger flowers and were overall more uniform across each treatmentgroup (FIG. 18A). The control group had smaller flowers and greatervariability in plant size, which corresponded to less plant biomass(FIG. 18B).
